so the first half is a trail run and then it's a road run back?
Mostly paved, then some gravel but nothing crazy, then road back.
Tough climb starts 30 m in then once you finish the climb, it undulates a bit up too, then down to the water which is essentially flat.
Ive been curious if I would miss judge the climb pace at some point. Too slow and you can't make up the time in the second halg. Too fast and you will hurt too much.
