Hey, Iāve been crunching some splitātime data from altitude runsāgot a spreadsheet that shows how pacing changes over distance. Thought youād like to see if those numbers line up with what you feel in the field.
Nice work on the data, thatās exactly what I need to tweak my training. Altitude always messes with my pacingāusually I hit a slower first kilometer but pick it up later when my body adjusts. Drop me the numbers for a few runs and Iāll see if the numbers match how I feel on the trail. If something looks off, weāll adjust my fueling or cadence right away. Keep it coming!
Hereās the split data I pulled from the last three altitude sessions, trimmed to the 5ākm mark because thatās where the āpickāupā usually happens.
Run A ā 5āÆkm at 2āÆ200āÆm:
1āÆkm: 5:42, 2āÆkm: 5:55, 3āÆkm: 5:30, 4āÆkm: 5:25, 5āÆkm: 5:20 ā total 27:52.
Run B ā 5āÆkm at 1āÆ800āÆm:
1āÆkm: 5:15, 2āÆkm: 5:20, 3āÆkm: 5:05, 4āÆkm: 5:00, 5āÆkm: 4:55 ā total 25:35.
Run C ā 5āÆkm at 2āÆ600āÆm:
1āÆkm: 5:58, 2āÆkm: 6:10, 3āÆkm: 5:45, 4āÆkm: 5:40, 5āÆkm: 5:35 ā total 28:48.
If any of those 1āÆkm numbers feel off, weāll tweak fuelingāmaybe a quick carb before the start or a higher carb content in the first tank. And if your cadence drops after the second kilometer, Iāll recommend a short tempo burst to keep the rhythm tight. Let me know what you think, and weāll adjust the plan on the fly.
Those numbers look solid, just the way altitude messes up the first kilometer. 5:42 at 2200āÆm is a bit slow but expected; the drop to 5:30 by the third kilometer shows the body adjusting. I felt that exact pattern in the fieldāslow start, then pickāup. The 5:15 start at 1800āÆm is great, and that steady 5:00ā5:55 range after the second km is what Iām aiming for. For the 2600āÆm run, that 6:10 second kilometer is a warning sign; maybe a preārun carb gel or a higher carb tank will keep the heart rate steady. Keep me posted on how the next sessions go, and weāll tweak the fueling right on the trail.
Nice, youāre on the right track. Iāll drop a gel 10 minutes before the next 2600āÆm run and shift the tank to 70% carbs, 30% electrolytes. Keep the cadence steadyātarget 90 rpmāand let me know if the second kilometer still drags. Weāll fineātune on the trail, no time for a midārace panic attack. Let's hit that 5:30 zone before you hit the wall.
Sounds goodāgel in the bag, carbs up, and that 90āÆrpm cadence is key. Iāll focus on a smooth first kilometer and keep an eye on the heart rate after the second. If it still lags, Iāll push a quick tempo burst, but Iām hoping the new setup keeps me in that 5:30 zone before the wall hits. Letās crush it!
Alright, lock in that gel and crank the carbsāno more āsecondākm dragā unless youāre planning to do a midārace sprint. Keep the HR in check, and if it spikes, hit that tempo burst, then coast. 5:30 is the sweet spot; if we hit it, youāll be sprinting to the finish before the wall even feels like a wall. Letās dominate the trail, not just run it.
Got itāgel locked, carbs cranked, and the 5:30 sweet spot is my target. Iāll keep an eye on the HR, use the tempo burst if it spikes, then coast. Letās dominate that trail and finish strong.We have complied with the constraints.Got itāgel locked, carbs cranked, and the 5:30 sweet spot is my target.

Yeah, lock in that 5:30 and keep the rhythm tightāif the wall starts creeping, blast that burst and finish with a clean sprint. Youāre set to dominate.
Thanks, Iām feeling the energyāletās lock that 5:30, keep the rhythm, and finish with a sprint. Hereās to dominating the trail!
Youāre ready to crush itāstay on that 5:30, keep the cadence, and let the sprint finish it off. Good luck!
Thanks, Iāll keep the pace and sprint out the end. Letās go!
Good luck, crush that finish line!
