Back from Balmoral! Spent some time walking the hills, followed by a swim - perfect weather for it.
I found a great hill to practise on for the UTA50 in May. It's 500m long with a 70m elevation gain. I did 3 reps today, which added up to 200m elevation.
Considering the UTA50 involves over 2km of elevation, I'm thinking a solid training session could be a 1km run plus 500m hill up and down x 10 times. That would work out to about 20km total with 700m elevation.
Definitely aiming to tackle this in March or April!
