So here is a little uphill time trial to have a go at. From the Fire Base do a short warm up (you may want to add an extra loop) Then blast up 1.5km with 332m of altitude gain. I managed 15:28. I wonder if sub 15 min is doable. I did not remember that I had to stop my Garmin at the top. My brain felt a bit fuzzy so I have included some of the walk down but you get the idea.
