Three Sisters Marathon - August 2025

[Skydog]

Trying to run the sisters traverse standard route (or reverse) here in a few weeks and wondering what things look like up high.  Too much snow on north?  Better to start on south or north?  Recommendations for crampons for trail running shoes?  Any information is much apprecated.

Personally I like it with snow. Definitely go North to South. I wore BD aluminum strap-on pons on Altras when I did it in June one year. Worked well enough but obviously you should test it first. 

This will give you a good idea of how much snow to expect... https://www.mtbachelor.com/the-mountain/webcams/
