Decided to try and test the water today.
Dialled in a 100k and just decided to see how far I could get.
First few hours were ok, no problems with the pace
I hit the first 20k without a break, and then wanted to do 10km stints.
After about 40k the first cramp came in – needed more breaks which was effecting the pace quite a bit.
Decided to quit after 5 hrs. Teen had made lunch and it seemed a shame not to 🙂
