Mauna Kea. This is the true test of climbing, it's not just the vert here, it's the conditions, the lack of support and services, the altitude. 4,200m, 68km at 6%. Just 2 and a bit repeats of this beast and that's an Everest.... I wish it was that easy.

Next up it's the truly daunting Colle Delle Finestre. Recently named the worlds most epic climb by GCN, this is a 18km climb that you'll do well to make one ascent of with 8km of gravel, an average of 9.4% and zero respite all at the mercy of the the weather.

Dave's going to be knocking out over 5 reps on a climb that is beautiful as it is brutal... all just 3 days after battling the Rocacorba.
