The Course
Photo: YouTube / Josh Reid
Four days through the Maasai Mara ecosystem. Wildlife crossings. Cultural immersion. Volcanic terrain. It's a safari with a timing chip.
Signature challenge: It's not one thing—it's everything. Heat. Altitude. Dust. Distance. Wildlife. Four days of sensory overload.
?
MILE
Savanna Introduction
150km across the open Mara. The scale hits you. So does the dust.
?
MILE
Volcanic Highlands
Climbing into the highlands. Altitude starts to bite. Heat doesn't quit.
?
MILE
Queen Stage
The longest, hardest day. Remote. Exposed. Beautiful. Breaking point for many.
?
MILE
Victory Lap
Final stage to finish. Wildebeest may join your peloton. Not a joke.

From the Field
You're riding through the Mara and there's zebras crossing right in front of you. You just have to stop and take it in because nothing in cycling prepares you for this.

Day three broke me. The heat, the dust, the altitude — everything compounds. But crossing that finish line knowing you survived all four stages is something else entirely.

3 WORKOUTS BUILT FOR THIS RACE
Each workout below is selected from our archetype library based on Migration Gravel Race’s specific demands. Click any workout to see the full execution protocol.
DurabilityDouble Day Simulation
2hr (AM+PM)+
Two sessions in one day — AM endurance, PM intensity. Trains the double-day fatigue of multi-day events.
404 miles. Your legs will beg to quit after 120. This trains the power output you need from mile 130 onward.
EXECUTIONThe AM ride loads fatigue. The PM session tests your ability to produce quality power on pre-stressed legs. This is what stage racing and back-to-back hard days feel like. Don’t skip the AM ride — that’s the whole point.
CADENCEAM: 85–90rpm easy | PM: 85–95rpm on intervals
POSITIONAM: comfortable, any position | PM: race position for intervals
RPEAM: 3–4 | PM intervals: 7–8
RACE-SPECIFIC: MIGRATION GRAVEL RACE
HEAT PREP June in Maasai Mara, Kenya — 15-30°C (59-86°F), equatorial sun, possible afternoon storms. Heat + altitude combination that compounds daily. Begin heat acclimatization 10–14 days before Migration Gravel Race — 20–30min sauna sessions or midday rides in full kit. Pre-load sodium 48 hours out. Target 500–750ml/hr with electrolytes on race day. Race-day realities: Equatorial sun at altitude; Heat + UV + altitude = dehydration risk that compounds daily.
NUTRITION Ultra-distance fueling for 404 miles: 80–100g carbs/hour from mile 1 — don’t wait until you’re hungry. Practice your exact race-day nutrition in every long training ride. Carry backup calories. 404 miles burns 8,000–12,000+ calories — you cannot replace them all, but you must try.
ALTITUDE Migration Gravel Race with 26,000ft of climbing, much of it above 8,000ft demands altitude preparation. Arrive 5–7 days early for acclimatization. Expect 5–15% power reduction at altitude. Increase iron intake 4 weeks out. Hydrate aggressively — altitude increases fluid loss by 20–40%. Equatorial sun at altitude; Heat + UV + altitude = dehydration risk that compounds daily.
TERRAIN Mixed terrain at Migration Gravel Race requires surface adaptability. Include weekly rides on red volcanic dust and savanna trails to build confidence. Expect: red volcanic dust, hard-packed savanna trails, game reserve roads.
EnduranceTerrain Simulation Z2
2hr+
Zone 2 with rolling terrain simulation — undulating power that builds fat oxidation.
Every hard session works better with a bigger aerobic base. At 404 miles, base fitness is the difference between racing and surviving.
EXECUTIONStay in Zone 2 the entire time, but undulate your power to simulate rolling terrain. The rises push the top of Z2; the valleys ease off. This builds terrain-responsive pacing without leaving the aerobic zone. Your body learns to modulate power without thinking.
POWERRises: 72–78% FTP | Valleys: 62–68% FTP | All within Zone 2
CADENCERises: 80–85rpm | Valleys: 88–92rpm
POSITIONAlternate: hoods on rises, drops on flats. Build position endurance.
RPE3–4 throughout — never hard, but never mindless

HVLI ExtendedBack-to-Back Long
2.5hr + 2hr+
Saturday long ride, Sunday medium ride — back-to-back volume that mimics multi-day fatigue.
404 miles rewards fat oxidation. This volume work shifts your fuel mix so you're still burning fat at hour 5, not bonking at hour 3.
SAT: Z2 2.5hr
SLEEP
SUN: Z2 2hr

STRUCTURESaturday: 2.5hr Zone 2 | Sunday: 2hr Zone 2 with 3×5min tempo inserts
EXECUTIONSaturday loads the fatigue. Sunday tests your ability to ride steady on tired legs. The Sunday tempo inserts at minutes 45, 75, and 105 simulate the surges you’ll face late in a race when your legs are already cooked. This is durability training.
POWERBoth: 65–70% FTP | Sunday tempo: 76–82% FTP
CADENCESaturday: 85–90rpm | Sunday: 85–90rpm, 90–95rpm on tempo inserts

What is the climate like at Migration Gravel Race?
+
Historical weather data shows average highs of 71°F and lows of 53°F, with a 43% chance of rain on any given day. Heavy rain before Stage 1 created "thick mud we had to ride, or walk, through something that was more like clay, with our wheels unable to keep turning." Stage 2 started "quite cold, with thick fog" at 2,300m elevation. The 2025 edition saw "crosswinds that would shape the day" on Stage 1 and "long climbs and high heat" on Stage 2, showing the equatorial weather's tactical impact. Among the most weather-friendly events, easier than Badlands.[2]
How are the logistics for Migration Gravel Race?
+
Flying into Nairobi, staying at Holiday Inn Two Rivers, then transport to Maasai Mara basecamp is straightforward but inflexible. Lukas Baum's early puncture recovery shows mechanical support exists, though riders handle their own repairs. Haley Hunter Smith's full-suspension MTB with gravel handlebar setup demonstrates equipment flexibility, but you're locked into race HQ's schedule with 14:00 bike build on Mara Day. "The bonds forged over four days of riding, camping, and commiserating in the Maasai Mara helped ease the painful parts."[3]
How adventurous is Migration Gravel Race?
+
Stage 3 featured "knee-deep water crossings, navigated herds, and dodged thorn bushes as nature took center stage." Riders regularly encounter "wildebeests, zebras, giraffes, antelopes" on course, with lions spotted 500 meters from camp. "blood, sweat and tears, flat tires and broken souls, that's the price here and it is still a bargain." Wildlife has absolute right of way.[10]
How prestigious is Migration Gravel Race?
+
Elite field includes Unbound winner Ian Boswell, former WorldTour pros Hans Becking, Chad Haga, David Millar, and rising stars like Samuel Kagiri. "absolutely on my bucket list" after seeing race footage. The race draws comparison to Cape Epic for difficulty level, with one finisher describing it as "the most amazing experience of my life" due to wildlife encounters during racing.[6]
Should I race Migration Gravel Race?
+
Yes, if you can afford it and can get a spot. Migration is the gravel adventure of a lifetime. No other race combines this level of support, experience, and pure adventure. Just be ready for the price tag and the cumulative stress of four consecutive days.
