History was made in London. This is the story behind Yomif Kejelcha's debut sub-two marathon, and the fueling plan that got him there.
In just 11 weeks of specific preparation, Ethiopian athlete Yomif Kejelcha broke the two-hour barrier in his first marathon. No prior experience at the distance. No margin for error.
It's the kind of performance that stops you mid-scroll. A track athlete — one of the best in the world at shorter distances — lines up for his marathon debut and runs 1:59:41. The work behind it was as precise as the result.
The preparation started in January with barely 12 weeks on the clock. The challenge wasn't just fitness — it was a full physiological shift: adapting a track-built body to the demands of 42.195 kilometers.
The first obstacle came early. During an initial visit to Ethiopia, the team discovered Yomif was dealing with pain behind his knee that was disrupting his training. Some days he could run. Others he couldn't. The call was made immediately: fly him to Spain for assessment and treatment with Dr. David Capapé. Five days later, he was back to training pain-free. From that point, everything pointed toward London.
A Race Against Time
With the clock ticking, the team's first priority was identifying what could be improved quickly and what needed to be built over time. From there, a daily monitoring process began — combining how Yomif felt with what the data showed.
Blood work every three weeks. 24-hour variable tracking. Daily nutrition adjustments. Supplementation dialed to each specific session.
"The biggest challenge was energy. Athletes who come from winning on the track are pure fuel, but the marathon demands something different: efficiency, metabolic endurance, and the ability to sustain effort for 42 kilometers." — Alfonso, nutritional and strategic lead
The focus: progressively build training volume to improve metabolic flexibility and mitochondrial density, close any caloric gaps, and nail in-training fueling.
One Job: Just Run
In the final 48 hours before the race, the goal was simple — eliminate every decision Yomif didn't need to make.
The team built an hour-by-hour plan: food weighed and prepped in his room, training schedules managed, bottles prepared, supplementation timed, rest structured. Every detail was handled so Yomif could show up at the start line with one thing on his mind.
"The idea was simple: for him to feel that everything was under control and that he only had to run." — Alfonso
The Nutrition Plan
The fueling strategy was built around one number: 580 grams. That's where the team wanted Yomif's glycogen stores at the start line.
At 59.5 kg bodyweight, the estimated carbohydrate burn rate was 290 grams per hour. Between pre-race intake and in-race fueling, the plan accounted for 287 grams of carbohydrates. The margin between what he'd burn and what he'd take in was razor thin.
An added wrinkle: most of the testing happened at altitude in Ethiopia. Some sea-level values had to be estimated. The team was confident in the projections — but there was no room for slip-ups.
Race Day Fueling
The strategy ran across three phases: pre-race preparation, a pre-start protocol, and in-race intake.
The day before, Yomif took two doses of Unusual Nitrous — one mid-morning, one early evening — to arrive at race day primed.
Race morning, he consumed a custom prototype drink (750 ml, taken gradually) between 6:15 and 7:30 AM. After warm-up, he took Unusual Gel 45 CAF 100 with small sips of water.
On course, the plan hit every 5 kilometers:
Km 10: Reset Gel + 20 ml — left side
Km 15: 63 ml Unusual Fuel — right side
Km 20: Gel 45 CAF + 40 ml — right side
Km 25: 62 ml Unusual Fuel — left side
Km 30: Reset Gel + 20 ml — right side
Km 35: 58 ml Unusual Fuel — right side
The instruction: don't rush it. Take the bottle, hold it, drink slowly — even if it takes a few minutes.
Reducing Energy Cost Everywhere Else
Nutrition was only part of it. The team also built a detailed race execution strategy — wind direction and intensity mapped by time slot, course sections modeled, tactical positioning planned every 5 kilometers.
"We knew that, among the contenders, we were probably the least efficient athlete for the distance. That's why we had to reduce energy cost in every possible detail and, at the same time, execute optimal intake." — Alfonso
The strategy worked almost perfectly.
Two Bottles
The only thing that didn't go to plan: Yomif missed two bottles. One slipped at kilometer 25. He didn't see the table at kilometer 35.
Between them: 19 grams of carbohydrates. Small on paper. Potentially everything in a race operating at the physiological limit.
At kilometer 41 — 1.2 km from the finish — he ran out of energy.
After crossing the line, Yomif found Alfonso and said: "I'm sorry, Alfonso. I missed two bottles and lost the race."
He didn't yet understand what he'd just done.
This Is Only the Beginning
1:59:41. First marathon. Under two hours.
Every variable measured — training, recovery, nutrition, supplementation, wind, positioning, energy management. Eleven weeks to build something most athletes spend years chasing.
"I am eternally grateful to Yomif Kejelcha for his professionalism, his trust, and his absolute commitment. In 11 weeks, it was impossible to do more, control more details, or make better use of the time we had." — Alfonso
As Yomif put it best: "This is only the beginning."
