May climbing Mont Blanc have an impact on training for ultras?

    Hi there,

    I’ve got two races next year, the first one and my main objective is at the end of July (110km, 6500m D+) and a secondary objective is around mid October (94km, 6200 D+).
    But I’d also like to climb Mont Blanc next summer, so my question is; might climbing Mont Blanc be complimentary or detrimental to my training-performance? I thought to give it a go at the end of June, effectively a month before my main goal, and use it as a long day out (time on foot) at a low HR. Would that have a positive or negative impact? Or none? Would it be smarter to do it in between races (at some point in August) if the performance on the second race is not a priority for me?

    Thanks in advance!

    I think that will be very complimentary 🙂 First for the mind, variety in training is good. From physiological perspective, I guess that can top up your high-volume mileage and you start to slowly trail down from there; the big backpack will be good for overall strength.

    I’d assume your are talking a 2-day ascent though. For most people, a single push from the valley would count as utilization and not capacity training. Altitude will also take a big toll if you have not done a few 4000m peaks in the weeks and months ahead.

    Finally, June is a bit early in the season if you had planned to do it on foot instead of ski.

    If you allow enough recovery afterward it should be fine. Good luck!

    Wait… I just noticed that your other events are ultras. I thought they were other mountaineering events.

    If you think that you can recover quickly enough from Mont Blanc then it should be an issue. If recovery will take a long time, then it could impact your run training. It really depends on your training leading up to it.
