Two Oceans Marathon Training Guide 2027: 56km Ultra, Chapman's Peak and Constantia Nek

Cape Town's Totalsports Two Oceans Marathon has earned its nickname, "the World's Most Beautiful Marathon," through geography, drama and timing. The 56km Ultra sends runners from Newlands through the southern suburbs, False Bay, Fish Hoek, Chapman's Peak, Hout Bay, Constantia Nek and back toward UCT, stacking postcard scenery on top of genuinely hard late-race climbing. The Half Marathon has its own sting, with Southern Cross Drive turning 21.1km into something far more interesting than a flat suburban jog. And both events, for 2027, are genuinely bigger than they've ever been.

Two Oceans Marathon at a Glance

A Quick Note on Distances

Unlike most races in this guide series, Two Oceans doesn't offer a standard 26.2-mile marathon. Its two flagship events are the 56km (34.8-mile) Ultra Marathon and the 21.1km (13.1-mile) Half Marathon — both run under the "Two Oceans Marathon" banner, a name that predates the modern convention of "marathon" meaning strictly 42.2km. The event week also includes a Night Run, an International Friendship Run, and Trail Runs at 16km and 24km. This guide focuses primarily on the Ultra, with a section on the Half.

Why This Race Is Worth Your Attention

The Totalsports Two Oceans Marathon is one of South Africa's most iconic sporting institutions, run by the Two Oceans Marathon NPC in partnership with staging and commercial partner Stillwater Sports. The 2026 Ultra Marathon earned IAU Golden Label status, cementing its place among the world's elite ultra-distance road races. The 2026 edition saw Gerda Steyn claim a record seventh Ultra Marathon win, with Arthur Jantjies taking the men's title in a stunning finish — results that routinely draw international attention.

For 2027, the event is undergoing a genuine transformation: a new Event Week format spreads the Night Run, International Friendship Run, Trail Run, Half Marathon and Ultra Marathon across five days (March 31 to April 4), each with its own moment in the spotlight, building toward the Ultra Marathon as the week's grand finale. Both flagship events are also expanding significantly — the Half Marathon from 17,000 to 21,000 entrants, and the Ultra Marathon from 14,000 to 21,000 — making 2027 a more accessible year than recent, more oversubscribed editions.

Ultra Marathon Course Profile and Elevation

The Two Oceans Ultra Marathon starts on Main Road, Newlands and finishes at the UCT Rugby Fields, tracing a 56km loop around the Cape Peninsula's southern reaches. The course carries roughly 700 meters (2,300 feet) of cumulative elevation gain, concentrated in two genuinely difficult climbs: Chapman's Peak Drive and Constantia Nek.

The course's defining trap is its reputation for an "easy first half." It isn't quite true. A gradual but consistent climb through the first five kilometers, taking runners through Wynberg, surprises plenty of first-timers who arrive expecting a flat start. From there to around 14km the route eases, before genuinely flattening out through Muizenberg, St James and Fish Hoek — until the real work begins at Noordhoek, around the 28km mark.

Chapman's Peak Drive (from ~28km)

The route climbs "Little Chappies" first — about a kilometer of steep climbing — followed by a brief reprieve before the main event: a 2.5km climb that's steep and genuinely hard. A "fake top" partway up fools first-timers into premature celebration before one more turn reveals the true summit, rewarded with what's routinely described as one of the best views in road racing anywhere in the world, overlooking Hout Bay.

The Hout Bay descent

A long, steep-cambered downhill follows, with the final 600 meters on cement — a genuine quad-buster that catches runners who treat the descent as free recovery.

Constantia Nek (from ~40km)

Contrary to popular belief, the climbing toward Constantia Nek actually begins at the Hout Bay circle (40km), not at the marathon mark as many assume. The Nek itself — roughly 2km of climbing around the 50km mark — is one of the hardest late-race climbs in major road ultrarunning, arriving with just 6km left after 50km of accumulated fatigue.

The final stretch

After cresting the Nek, runners face tired legs and camber-heavy roads through Newlands Avenue before reaching Southern Cross Drive and Newlands, then a stretch of good downhill running from Kirstenbosch's top gate to within 2km of the finish. The route continues past Kirstenbosch to Bishops Court for a U-turn, a recent course adjustment adding roughly 1km to the measured distance, before the final push via Chet's Hill to the finish on the UCT grass.

What kind of runner does the Ultra reward?

• Runners who resist the temptation to bank big time in the deceptively "easy" first half
• Runners who train specifically for two well-separated major climbs, arriving fresh at Chapman's Peak and disciplined at Constantia Nek
• Runners with durable quads for a long, steep-cambered descent into Hout Bay
• Runners who can hold form and keep moving forward on tired legs through the final, camber-heavy miles

Ultra Marathon Course Breakdown by Segment

Start to 5km: The deceptive climb through Wynberg

The Ultra starts in the dark, and the early miles carry a gradual but consistent climb through Wynberg that surprises runners expecting a flat start.

Pacing instruction: Don't be alarmed if you're working harder than expected this early — this is normal, and everyone around you is experiencing the same thing.

5km to 14km: Settling in

The route eases from Wynberg, giving back some of the early elevation before flattening out.

Pacing instruction: Use this section to settle into rhythm and recover mentally from the surprising opening climb.

14km to 28km: Muizenberg, St James, Fish Hoek and Noordhoek

Runners reach Muizenberg around 14km with the sun rising over False Bay, continuing through St James and Fish Hoek before climbing toward Noordhoek village at the 28km mark, passing Sun Valley Mall along the way.

Pacing instruction: This is genuinely fast, flat terrain — a good stretch to bank a modest amount of time without overcommitting, since real work is about to begin.

28km to ~35km: Chapman's Peak Drive

"Little Chappies" (about 1km, steep) arrives first, followed by brief relief, then the main 2.5km climb of Chapman's Peak Drive — steep, hard, and featuring a false top before the true summit.

Pacing instruction: You'll likely feel fresh here, which is exactly the trap. Don't push just because you can — save your legs for what's still 20-plus kilometers away.

~35km to 40km: The descent into Hout Bay

A long, steeply cambered downhill follows the Chapman's Peak summit, with the final 600 meters on cement — one of the most quad-damaging stretches on the course.

Pacing instruction: Run this downhill under control. Free speed here comes at a real cost to your quads later.

40km to 50km: Constantia Nek

The climbing toward Constantia Nek actually begins at the Hout Bay circle (40km), well before the marathon mark most runners expect it to start, with the Nek itself — roughly 2km of hard climbing — cresting around 50km.

Pacing instruction: This is where the race is genuinely won or lost. Expect to run 40–50 seconds per kilometer slower than your average required pace here, and don't panic about it.

50km to the finish: Newlands, Kirstenbosch and UCT

After cresting the Nek, tired legs and cambered roads make Newlands Avenue and Southern Cross Drive tougher than the terrain alone would suggest, before a genuinely fast downhill stretch from Kirstenbosch's top gate. The route continues to Bishops Court for a U-turn before the final push past Kirstenbosch's bottom gate, up the M3 and Chet's Hill to the finish on the UCT grass.

Pacing instruction: Rebuild toward your average pace as quickly as you can after the Nek. Take advantage of the Kirstenbosch downhill, but stay controlled — your legs have taken 50-plus kilometers of damage, and this isn't the place for a reckless final sprint until the UCT grass is actually in sight.

Half Marathon Course Overview

The 21.1km Two Oceans Half Marathon starts on Main Road, Newlands and finishes at the same UCT Rugby Fields as the Ultra, but takes its own route through Claremont and Wynberg before entering the lush Constantia valley. Its signature challenge is the climb up Southern Cross Drive, which offers genuinely panoramic views in exchange for real effort, before a fast return through Newlands and a leafy, shaded stretch past the Kirstenbosch Gardens entrance on the way to the finish.

Pacing instruction for the Half: Respect the Southern Cross Drive climb the same way Ultra runners respect Constantia Nek — it's the course's defining test, and it arrives with real racing still left to do afterward.

Two Oceans Pacing Strategy

The Ultra rewards a very specific pacing discipline: run the "easy" first half at close to average pace (not faster), treat Chapman's Peak with restraint even when you feel fresh, and hold real reserve for Constantia Nek, where 40–50 seconds per kilometer slower than average is normal and expected.

General Ultra Marathon pacing framework (relative to your average required pace)

How to Train for Two Oceans

Training for the Ultra should emphasize genuine climbing and descending durability, plus the discipline to run a deceptively easy first half conservatively.

1. Train two well-separated climbs into long runs

Rehearse climbing when relatively fresh (mimicking Chapman's Peak) and climbing again on tired legs much later (mimicking Constantia Nek) within the same long run.

2. Practice controlled, quad-protective downhill running

The descent into Hout Bay is genuinely damaging if run recklessly. Train downhill running at a pace that feels conservative, prioritizing form over speed.

3. Rehearse restraint on "easy" terrain

The biggest pacing error at Two Oceans is treating the first 28km as banking territory. Practice holding back on flat, fast training terrain so it becomes automatic on race day.

4. Build serious long-run volume

At 56km, the Ultra demands genuine ultra-distance training — back-to-back long run weekends and progressively longer efforts are standard for a race of this length.

5. Build a training block appropriate to your experience

Ultra Marathon entry via the Blue Number Club requires proven qualifying performances; first-time ultra runners should build a dedicated marathon base before attempting a structured Two Oceans build.

Weather: Cape Town Autumn

Early April in Cape Town sits in the shoulder between summer and winter, with average highs around 22.5°C (72.5°F) and lows near 15°C (59°F) — generally favorable conditions for endurance racing, though the Ultra's early, dark start means real temperature swings across the day. Expect an average of around six rainy days across the month as the first winter cold fronts begin arriving, and light-to-moderate winds.

Heat outlier

While the notorious "Berg wind" — a hot, dry wind that can push temperatures toward 35°C (95°F) — is more typical of summer, unseasonably warm race-day conditions are not unheard of in early April. If the forecast runs warm, adjust your early effort down and take hydration more seriously, especially given the exposed Chapman's Peak and Constantia Nek climbs.

Cool/wet outlier

An early cold front can bring rain and cooler temperatures, especially given the pre-dawn start. Dress in layers you can shed once the sun is up.

Fueling Strategy

At 56km, the Ultra demands genuine ultra-distance fueling discipline — well beyond standard marathon nutrition. Most ultra runners should aim for 60–90+ grams of carbohydrate per hour, adjusted upward for the extended duration and the real climbing demands of Chapman's Peak and Constantia Nek. Late Ultra stations include water, Coke and Powerade, with official examples at 49km, 52km and 54km; check official race materials for full station placement closer to 2027.

Suggested fueling checkpoints aligned to the course

• First fuel within the first 30–40 minutes, before the Wynberg climb fully sets in
• Regular fueling every 30–45 minutes through the flat Muizenberg-to-Noordhoek stretch
• A solid fuel intake just before Chapman's Peak (around 27–28km), since the climb will slow your ability to fuel comfortably
• Continued regular fueling through the Hout Bay flats before Constantia Nek
• A final push of carbohydrate and electrolytes before the Nek (around 48–49km) to carry you through the course's hardest climbing

Mental Strategy for Race Day

Start to 5km: Don't panic about the climb

Wynberg, in the dark. Everyone is surprised by this — it's not a sign anything is wrong.

5km to 28km: Settle in and enjoy the scenery

Muizenberg. St James. Fish Hoek. False Bay on your left. This is the "easy" section — run it evenly, not aggressively.

28km to 35km: Respect Chapman's Peak, even feeling fresh

Little Chappies. The false top. The real summit overlooking Hout Bay. The views are extraordinary — the discipline not to race them is what separates a good Two Oceans from a bad one.

35km to 40km: Descend with control

The steep drop into Hout Bay. Free speed here is borrowed against your quads later — don't overspend it.

40km to 50km: Climb Constantia Nek with everything you saved

The hardest late-race climb on the course. Everything you didn't spend earlier is currency here. Expect to slow significantly, and don't fight that reality.

50km to the finish: Rebuild, then finish strong

Newlands. Kirstenbosch. Bishops Court. Chet's Hill. The UCT grass. If you managed the two climbs with discipline, this is where "the World's Most Beautiful Marathon" gives you its finish.

Logistics: Hotels, Expo and Race Weekend

Where to stay

Newlands and the southern suburbs near UCT put you close to both the start and finish for either event; central Cape Town is a reasonable alternative with easy access via the well-established race-day transport network.

Getting to the start

Given the scale of the event (up to 21,000 runners per distance), plan race-morning logistics well in advance — check official parking, transport and walking-route information closer to 2027, since both events start in the pre-dawn hours.

Race pack collection and expo

Race packs are collected in the days before each event; check the official Two Oceans Marathon site for confirmed 2027 dates, times and locations closer to race week.

Entry for 2027

Blue Number Club (BNC) entries open July 15–22, 2026; the general ballot opens August 5, 2026, for both the Half Marathon and Ultra Marathon. Charity entries are available through participating charities such as the 9 Miles Project.

Event Week schedule

Wednesday, March 31 (Night Run, 8km) → Thursday, April 1 (International Friendship Run, 4.5km) → Friday, April 2 (Trail Runs, 16km and 24km) → Saturday, April 3 (Half Marathon) → Sunday, April 4 (Ultra Marathon).

Two Oceans Marathon FAQ

When is the 2027 Two Oceans Marathon?

Event Week runs March 31 to April 4, 2027. The Half Marathon is Saturday, April 3; the Ultra Marathon is Sunday, April 4.

Is there a standard 26.2-mile marathon?

No. The event's two flagship distances are the 56km Ultra Marathon and the 21.1km Half Marathon — the "marathon" in the race's name reflects its historic branding rather than the modern 42.2km standard.

Are there cutoff times?

Yes. The 56km Ultra has a final cutoff of 7 hours from the start gun time of the last batch, while the Half Marathon has a final cutoff of 3 hours 30 minutes from the start gun time of the last batch. Intermediate cutoffs may also apply for road-opening and safety reasons — they should not be treated as pacing targets. Build a race plan that gives you margin, especially before Constantia Nek.

How do I enter?

Through Blue/Yellow Number priority entry (for qualifying returnees), the general ballot, or a charity entry. For 2027, Blue Number Club entries open July 15–22, 2026, and the general ballot opens August 5, 2026.

How big is the race?

For 2027, both flagship events expand to 21,000 entrants each — up from 17,000 (Half) and 14,000 (Ultra) previously.

What's the weather like?

Early April in Cape Town typically brings average highs near 22.5°C (72.5°F) and lows near 15°C (59°F), with occasional early winter cold fronts and a real, if less common in April, chance of hot Berg wind conditions.

Is this a good first ultra marathon?

It can be, with appropriate ultra-distance training — but the two major climbs, especially Constantia Nek arriving after 50km, mean it rewards genuine preparation over marathon fitness alone.
