Sounds like every long run I ever do! No matter the pace (or nutrition/water), ~18 miles in... bang. Decided I'm better suited to shorter races so sticking to halves and below now.
So... you trading in the 620 for the ultras, Steph? I'm tempted as it is almost everything the 620 is and more.
Ahh - I see now. If you get enough miles in beforehand, then that 50miler will just blow the cobwebs out of your legs before the "race"
50 miles the week before Loch Ness?! Utter madness I say! I may have to back Andi now Surely your longest LSR should be 2-3 weeks out?
What software is that (graph and summary)?
