I'm joining the MR question party. Doing a slower ascent of Whitney via the MR in mid October. Totally understand the risk of weather, and not going up if there's any major snow/ice.

However, my friend and I would rather play safe than sorry. Last year we turned around on Mt. Russell because we didn't bring a rope and didn't feel comfortable at the final 400 meters of the east ridge of Mt. Russell.

Do people do running belays on MR? What's the "sketchiness" of this route compared to the east ridge of Mt. Russell?
