is my math off?? 40 miles in 90 mins on the gym bike 26.6 average speed...?
no hills indoors!!!
yesterday I came home from a camping trip, fully loaded with gear, 45 miles.
last year i did my first 50 miler (no gear) so decided after arriving home, to head off to the shop and back adding to a total a bit over the 50, very happy with that. then cooked dinner.
50 miles with gear - a different bucket of spuds!
I am not what fit used to be for me not by any stretch, am on Blood pressure meds, was starting out knackered from previous days runs. so it should be easy enough IMO.
learnt a good lesson, keep topped up with energy drinks after about 20 miles, and stop when you think you should, even if its going up a hill, its amazing what 10 yards pushing a bike will do for your legs in terms of a breather and nice rest.
honestly though, if you think you can't manage 50 (it is a mental block
) then try 40, try 30. just do what you can and then if need be increase it by 5 miles, till your there, don't get caught up on "can I? - But I might FAIL!!??"
first thing is to enjoy it!
PS. IMO this figure of eight thing might be a bit of a disincentive, I find HAVING to go all the way home spurs me on, there is no other option
YMMV
