Yes maybe a lot
It was actually 65miles then the warm up part of spin which for me is 20 mins standing climb, then the spin session then a ride home.
I try and do that on no food and water which okay again many say Is not good but it learns you to dig deep.
Its surprising how you can draw on that in a long fell race or a long ride in the future.
Its certainly not excessive though.
You can hydrate by wiping the sweat off your cycling cap and drinking that. ( thats not a joke).
It was all worth it just to see the sun going down over Beeley Moor.
