Get My Free Route 66 Plan PreviewThe Williams Route 66 Marathon in Tulsa is not a flat, sleepy late-fall marathon. It is a rolling urban road race with early hills, long stretches of well-supported pavement, strong neighborhood energy, and an optional 0.3-mile Center of the Universe Detour for runners who want to turn their marathon into something closer to 26.5 miles.
The key to training well for Route 66 is straightforward: build aerobic durability through the Oklahoma summer, practice controlled hill effort, and arrive ready to run the first half patiently so the course gives you something back later. The miles 17–20 climb is the race’s defining challenge. What you do before it determines what you have left for it.
This guide covers the course, the elevation, the training demands, the November weather and how to pace and fuel a rolling Tulsa marathon.

What Makes the Route 66 Marathon Different
Route 66 rewards patience. The course is urban, paved, and well-supported, but the rolling profile surprises runners who expect a simple late-fall road marathon.
The biggest training demands are four-fold.
Early-course hill discipline. The first half includes enough rolling terrain that chasing exact pace too early can backfire. Train by effort on hills, not by forcing even splits.
Summer-to-fall fitness conversion. For a November race, much of the training block happens in July, August and September. Expect slower training paces in Oklahoma heat and humidity. Use effort, heart rate, or adjusted pace rather than judging every run by raw split.
Durable legs for pavement. Much of the race is on roads and concrete paths. Long runs should prepare the quads, calves, hips and feet for repetitive impact on hard surfaces.
Race-day decision-making. The optional Center of the Universe Detour adds 0.3 miles. It is fun, memorable and very Tulsa, but it is not compatible with a tight time goal.
Route 66 is won in the second half. Run the early rollers by effort, bank energy through the flatter middle miles, and arrive at miles 17–20 with something left in reserve. Runners who spend the hills going out almost always pay for it on the way back.
Course Overview
The Williams Route 66 Marathon runs through Tulsa on a loop-style urban course that passes through neighborhoods, the city center and landmark Tulsa locations. The full marathon field starts alongside the half marathon and relay at 8:00 AM.
The course has four distinct characters. The first six miles are rolling with the most variation of the race. Miles 7–16 flatten considerably. Miles 17–20 bring the course’s most sustained climbing, with back-to-back uphills that demand controlled effort. The final 10K trends downhill on net, though not steeply enough to be free speed.
Miles 1–6: The Early Rollers
The opening miles of Route 66 are the course’s most active. Mile 2 climbs 45 feet, mile 3 drops 55, mile 5 adds another 35 and mile 6 drops 60. This is not mountainous running, but it is enough variation to make pace feel inconsistent and effort feel uneven.
The discipline here is simple: do not chase the downhill miles and do not hammer the uphill miles. Run by effort. Let the watch be what it is. Any runner spending this section trying to hold a precise flat-course split is setting up a difficult back half.
Miles 7–16: The Middle Stretch
After the early rollers, the course calms. Miles 7 through 13 are mostly flat-to-gentle, with small changes of 10–20 feet per mile rather than the swings of the early miles. Mile 15 is effectively flat. This is where the race should settle into efficient goal-pace rhythm.
Because these miles feel manageable, they carry a pacing risk: the temptation to bank time. Resist it. The miles 17–20 section is coming. Every second of extra energy spent in the middle is a second unavailable later.
Miles 17–20: The Climb Section
This is the defining section of the Route 66 Marathon. Mile 18 climbs approximately 50 feet and mile 19 climbs another 55. Back-to-back, at miles 18–19 of a marathon, those climbs are not trivial. Many runners who ran well through 16 will feel them acutely here.
The correct approach is effort-based: shorten stride, maintain cadence, let the pace drop and do not fight the hill with aggression. The detour decision point also falls in this part of the race. Runners already struggling at mile 17 should skip the detour without hesitation.
Miles 21–26.2: The Final Push
After the climb section, the course trends gently downward on net through the final miles. Miles 23 and 24 drop 20 and 25 feet respectively, and mile 26 drops another 25. This is not a dramatic downhill finish, but it is a slight structural advantage for runners who have managed their effort.
Mile 25 has a small +5 foot bump and the final 0.2 adds a 15-foot kick. Keep form through the last miles. The finish is close enough to feel and far enough to hurt if pacing has gone wrong.
Mile-by-Mile Elevation
Elevation changes are estimated from the official course elevation chart and FindMyMarathon data (updated November 2025). Use this as a training guide and effort-planning tool, not survey-grade surveyed elevation.
| Mile | Net change | Character |

| 1 | −20 ft | Gentle opening drop, settle in |
| 2 | +45 ft | First significant climb — run by effort |
| 3 | −55 ft | Downhill recovery, do not add speed |
| 4 | +5 ft | Near flat |
| 5 | +35 ft | Second climb of the early rollers |
| 6 | −60 ft | Biggest single-mile drop — do not chase it |
| 7 | −20 ft | Descending, course beginning to settle |
| 8 | −10 ft | Gently downhill |
| 9 | −15 ft | Gently downhill |
| 10 | +10 ft | Minor rise, flatter section |
| 11 | +15 ft | Minor rise |
| 12 | −10 ft | Gently rolling |
| 13 | −10 ft | Half-marathon mark zone, gently rolling |
| 14 | +5 ft | Near flat |
| 15 | 0 ft | Flat — settle goal rhythm here |
| 16 | +10 ft | Minor rise signaling the climb section ahead |
| 17 | +20 ft | Climb begins — ease back effort |
| 18 | +50 ft | Hard climb — shorten stride, hold cadence |
| 19 | +55 ft | Hardest mile of the race — effort-based only |
| 20 | +5 ft | Climb cresting, beginning to ease |
| 21 | −5 ft | Post-climb recovery — rebuild rhythm |
| 22 | −5 ft | Gently downhill |
| 23 | −20 ft | Final 10K, net downhill begins |
| 24 | −25 ft | Good late-race terrain — hold form |
| 25 | +5 ft | Brief rise, stay controlled |
| 26 | −25 ft | Downhill final mile |
| 26.2 | +15 ft | Short kick to the finish |
| Total | ~822 ft gain / ~839 ft loss | Rolling early, flat middle, climb miles 17–20, gentle final 10K |
The Center of the Universe Detour
The Center of the Universe is a famous Tulsa acoustic anomaly: a small bricked circle in the Brady Arts District where sound reflects and echoes in unusual ways. The Route 66 Marathon offers an optional 0.3-mile detour that routes marathoners through it.
The detour is free, open to all marathon runners, and requires no pre-registration. Runners who take it complete 26.5 miles — sometimes unofficially called the World’s Shortest Ultramarathon. The detour is one of the race’s most distinctive features and a genuine Tulsa experience.
If you are chasing a time goal, a BQ, or a personal record, skip the detour. It adds 0.3 miles and some extra time at a point in the race when economy matters. If you are running for experience and are comfortable with your pace, take it. You are unlikely to find a more Tulsa moment in any marathon.
Pacing Strategy
Route 66 does not reward even-split attempts through the early rollers. The correct approach is effort-based discipline in the first half, controlled output through the climb section, and execution in the final 10K.
Miles 1–6: effort-led, not pace-led
Let the hills dictate pace. Uphill miles should feel like marathon effort; downhill miles should not feel faster than marathon effort. Run by feel and let the watch be variable.
Miles 7–16: establish goal rhythm
Once the course flattens, settle into goal marathon pace on the flat miles. This is the section to find rhythm, not press it. Running these miles slightly conservatively sets up the climb section well.
Miles 17–20: controlled climbing
Ignore pace. Run by effort. Shorten stride, maintain cadence and accept that miles 18 and 19 will be slower. Runners who fight the climb at full effort almost always pay for it in miles 21–23.
Miles 21–26.2: race what you have
If pacing was disciplined, this section rewards it. The terrain is gently downhill on net. Hold form, fuel on schedule and run the final 10K as the race, not as a cooldown.
Sample pacing framework for a 3:30 marathon
| Segment | Course character | Target approach |
|---|---|---|
| Miles 1–6 | Rolling early hills | Effort-based; accept 8:10–8:20/mi on climbs |
| Miles 7–16 | Flatter middle | Settle goal pace, 8:00–8:05/mi on flat |
| Miles 17–20 | Climb section | Effort-based; accept 8:20–8:40/mi on miles 18–19 |
| Miles 21–26.2 | Gentle downhill finish | Race it — 7:55–8:05/mi if controlled through 20 |

How to Train for the Route 66 Marathon
Route 66 training has three demands that distinguish it from a generic marathon build: rolling-terrain conditioning, summer heat management, and patience practice for conservative early pacing.
1. Train on rolling terrain, not just flat roads
If your local routes are flat, add at least one rolling long run per week in the final 12 weeks. The goal is not to train on hills as steep as Route 66’s, but to teach the body to shift effort up and down without losing rhythm. Rolling routes on long runs are more useful than isolated hill repeats for this course.
2. Manage your summer training paces
A November race means July, August and September training in Oklahoma heat and humidity. Slower training paces in those months are not a problem — they are a correct adaptation. Run by effort or heart rate rather than raw pace and do not measure summer fitness by summer split times.
3. Practice goal pace on flat terrain late in long runs
The flattest miles on Route 66 (7–16) are where goal pace should happen. Simulate this in long runs: run relaxed and rolling for the first half of the long run, then target goal marathon effort or pace for the final 6–10 miles.
4. Build specific strength for the climb section
Miles 17–20 come when the legs are already fatigued. Add a small amount of hill repeats (60–90 seconds) and ensure some long runs include meaningful climbing in their later miles. The goal is not to become a hill specialist. The goal is to have controlled uphill form available late in the race.
5. True beginners: simplify the build
A 18-week plan peaks around 40–45 miles for a serious beginner-intermediate runner. True beginners should reduce weekday mileage, cap long runs at 18 miles, treat quality workouts as optional and prioritize finishing strong over chasing time.
Training block timing
For the November 22, 2026 race, an 18-week plan begins around July 20, 2026. A 16-week plan begins around August 3. A 20-week plan starts around July 6.
| Phase | Duration | Focus |
|---|---|---|
| Base building | Weeks 1–5 | Aerobic volume, heat-adjusted easy runs, rolling routes, strength foundation |
| Marathon-specific build | Weeks 6–13 | Rolling long runs, goal-pace flat work late in long runs, hill repeats, heat management |
| Sharpening | Weeks 14–16 | Controlled rolling effort runs, dress rehearsals, fueling practice |
| Taper | Final 2–3 weeks | Reduce volume, maintain rhythm, arrive with fresh legs |
November Weather in Tulsa
November in Tulsa produces the cool marathon conditions that most runners find favorable. NOAA climate normals for Tulsa show an average November high of around 61°F and an average low of around 39°F. The 8:00 AM start typically begins in the low-to-mid 40s, warming through the finish window into the 50s.
Wind is the variable. Tulsa’s open plains geography can produce noticeable wind on race day. A headwind on exposed sections adds meaningful effort cost without showing on the GPS. Layering for warmth at the start and planning for wind exposure on the course is good November race management.
Layering strategy
Start with throwaway layers for the corral and early miles. Gloves and a light disposable top are useful at 41°F race mornings. Once the effort builds through the early rollers, the body temperature rises faster than most runners expect.
Summer training note
Much of the Route 66 training block happens in summer heat. Oklahoma July and August temperatures regularly reach 95–100°F. Run in the early morning, hydrate aggressively, and use effort-based pacing rather than raw pace to avoid overtraining in heat.

Fueling Strategy
Cool November air suppresses thirst even when the body needs fluid. This is the classic fall marathon fueling trap: you feel fine, you skip a gel, and miles 22–24 remind you that cool weather does not suspend energy depletion.
Target 60 to 90 grams of carbohydrate per hour depending on body weight, gut training and race pace.
| Timing | Action |
|---|---|
| 10–15 minutes before start | Optional gel or sports drink if practiced |
| Miles 4–5 | First gel |
| Every 20–30 minutes after | Gel on schedule regardless of perceived effort |
| Miles 9–10, 14–15, 19–20 | Continue fueling; do not skip because you feel strong on the flat middle miles |
| Miles 17–20 | Critical window — fuel before the climb, not after you feel depleted |
| Every aid station | Take fluid even when not thirsty; cool air masks dehydration |

When is the 2026 Williams Route 66 Marathon?
The 2026 Williams Route 66 Marathon is scheduled for Sunday, November 22, 2026, as part of race weekend on November 21–22.
Is the Williams Route 66 Marathon a Boston qualifier?
Yes. The race is run on a USATF-certified course and is listed by the race as a Boston Qualifier.
Is the Route 66 Marathon hilly?
It is rolling rather than mountainous. The early miles (1–6) include meaningful climbs and drops. Miles 7–16 are flatter. The most demanding section is miles 17–20, which include back-to-back climbs of 50 and 55 feet. Prepare for rolling terrain throughout, not a flat course.
What is the Center of the Universe Detour?
It is an optional 0.3-mile detour for marathoners only, routing runners through the Center of the Universe, a famous Tulsa acoustic anomaly in the Brady Arts District. Runners who take it complete 26.5 miles. It is free, requires no pre-registration, and should be skipped for strict time goals.
What is the Route 66 Marathon course time limit?
Official on-course support (aid stations, course marshals) runs for 6.5 hours at a 16:30-per-mile pace. Electronic timing remains open for 7.5 hours.
What should I focus on in training?
Consistent mileage, rolling-terrain long runs, hill strength for the miles 17–20 section, heat-adjusted summer training pacing, marathon-pace flat work in the back half of long runs, and conservative early-race pacing discipline.
How should I approach the hills?
Run all uphills by effort, not by pace. Shorten stride, maintain cadence, and accept slower split times on climbs. The miles 18–19 back-to-back climbs are the hardest part of the course. Runners who arrive there already tired rarely recover well in the final 10K.
