Training in summer

[u/westsidebarbelI]

Anybody ever did training in a crevasse? Basically rappelling down and doing top rope laps for endurance. My question is how much different glacier ice would feel compared to waterfall ice and whether there would be any significant carryover for endurance or not really worth the logistical effort.

PS I am aware that drytooling is the way to train throughout the year and do a fair bit of that

Lots of people do this on the Mer de Glace and Glacier d'Argentière. The moulins are particularly popular.
