FAQ

Grossglockner Ultra-Trail foot questions.

  1. 01

    Where should I stop for foot care at Grossglockner Ultra-Trail?

    Grossglockner Ultra-Trail mile 14 at mile 13.6, Grossglockner Ultra-Trail mile 41 at mile 40.8. Those stops carry the most ground and descent behind them, so a sock change and a tape check pay for the minutes they cost.

  2. 02

    Which section of Grossglockner Ultra-Trail wrecks feet?

    Mile 2.5 to 5 drops 1,000 ft at 7.7 percent average grade. That is where toes meet the front of the shoe and heels start to lift. Pretape before it, not after.

  3. 03

    How do I keep my feet dry at Grossglockner Ultra-Trail?

    July highs reach 75 degrees F. Sweat saturates socks, skin softens, friction climbs. Change socks at every stop you can, run powder or a moisture barrier, and lean forward when you dump water on your head so it misses your shoes.

  4. 04

    Do I need dry socks for the cold sections of Grossglockner Ultra-Trail?
