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/

I have Caltopo premium which offers high def satellite photos every 48 hours. Happy to share some photos as you get closer to your objective.

Thanks for replies.  Abject failure on our first attempt.  Turns out moving quickly up and down that rock is harder than we imagined.  Especially coming off Middle Sister towards South.  Took way longer than we thought to get down.  Limped into Camp Lake and laughed at the thought of climbing South.  8 miles back to Pole Creek was easier.  Will try again next year.  Either in July when there's more snow or September when its a little cooler.  Fun, but brutal day in the mountains.
