Ultra-endurance cyclist Hannah Otto has pulled off one of the most extraordinary rides of 2026 – and finished it with a broken leg. The American set a Fastest Known Time (FKT) on Mount Kilimanjaro, becoming, by her own account, the first woman to climb and descend Africa’s highest peak by bike in a single day. The twist: she completed the final two miles pedalling with one leg after snapping her tibia in the mud high on the mountain.
What Happened
According to a report on road.cc (5 November 2026) and Otto’s own Instagram account, the 30-year-old tackled Kilimanjaro’s 5,895-metre (roughly 19,300-foot) summit by bike along a 42.6km route that threw everything at her: dense rainforest, pitches steeper than 40 per cent, rocky sections where she had to carry the bike on her back, and snow near the top.
With about two miles to go, disaster struck. Otto slipped in deep mud and, in her words, “my foot got caught and I felt the bone snap.” X-rays later confirmed a fractured tibia. Rather than abandon the attempt, she crawled to her bike, used it as a crutch, and rode the remaining distance pedalling with her one good leg.
Her husband, Clayton, reached her at the finish line, but Otto reportedly asked him not to touch her so that her effort would still count as unassisted. On Instagram she summed it up simply: “Mission accomplished! Dream come true!” She added that she believes “a dream may just be the most powerful thing in the world.”
Why It Matters
This was no amateur stunt chasing clicks. Otto is a decorated ultra-endurance athlete – a Leadville 100 champion and a serial FKT hunter whose résumé already includes the world’s longest climb in Hawaii, Utah’s White Rim, and the Kokopelli Trail. Her Kilimanjaro ride adds one of the most logistically brutal objectives in the sport to that list.
No official finishing time has been published yet, and the “first known woman” billing comes from Otto herself, so expect the record to be scrutinised and ratified in the weeks ahead. But the raw difficulty is not in dispute. Summiting and descending a nearly 6,000-metre volcano by bike in a day combines thin air, relentless hike-a-bike terrain, and the kind of technical descending that punishes an exhausted body – which is almost certainly how a world-class rider ended up breaking a leg within sight of the finish.
There’s a bigger story woven through it, too. Otto’s attempt has raised more than $65,000 so far for World Bicycle Relief, the charity that distributes rugged, purpose-built bikes to people in rural communities across Africa and beyond. Riding a bike up and down Kilimanjaro to fund bikes for the people who live in its shadow is the kind of narrative that travels – and deserves to.
What This Means For You
You are almost certainly never going to ride a bike up Kilimanjaro. But the fundamentals behind a feat like this scale down to any big day in the saddle – your first gran fondo, a bucket-list Alpine climb, or a long gravel event.
- Train the engine before the mountain. Rides like this are won on aerobic base, not heroics. Building that base is exactly what Zone 2 training is for, and it is the foundation endurance riders return to year-round.
- Climbing is a skill, not just fitness. Steep, technical gradients reward smart pacing and body position. Our guides on how to climb hills on a bike and building power with hill repeats cover the techniques that keep you moving when the road tilts up.
- Match the bike to the terrain. Kilimanjaro’s mix of rainforest, rock and snow is why this was a mountain-bike objective, not a road ride. If you are weighing up what you need for off-road adventures, start with the differences between a road bike and a mountain bike.
- Know when to stop. This is the uncomfortable part. Otto is a professional with a support crew, and even she gambled on her body. For the rest of us, pushing through a suspected fracture is not something to emulate – it is a medical emergency. Learning to tell the difference between deep fatigue and “something is badly wrong” is one of the most valuable skills an endurance rider can build.
The appetite for these challenges keeps growing. The same week Otto’s ride made headlines, the UCI Gravel World Championships were heading to Australia for the first time – another sign that long, hard, adventurous riding is having a real moment.
