Hi Pete,
Thanks for writing in.
That plan is pretty good for something like the Walker. You could replace the ‘additional ice climbing’ exercises with a basic fingerboard repeaters (7sec work/ 3sec rest) workout you can find anywhere on the internet and have something a bit more specific to the Walker. Before you go, I’d suggest doing a few very big climbing days with a lot of fast climbing and transitions, gear testing, etc. Perhaps this can also be in the Alps.
Be safe and let us know how it goes!
