As I recall it from 2011, which was a greater snow year we walked the upper most portion of Wheeler on the Breck side due to a large snowfield, it looked steep enough that even this year with no snow I will be walking on the SS. As I recall it I rode the entire descent, albeit cautiously. I am an average descender at best and I found it rideable but I rode carefully so as to not ruin my race 10 miles in. Hope this helps, should be a good race. I made the Boreus cutoff by about 30 minutes last year and I have lost a step this year so making the cutoff maybe a challenge in itself for me, cant' wait.
