Can you do 8 miles comfortably? Great run folk reckon you should be able to do 8 miles a month before the event. If you defer will you take it any more seriously / train more next year?
I'm entered and although I can do the 8 miles and probably a bit more I'm getting a bit worried but hoping momentum/adrenalin/atmosphere will help me with the last 5 miles.
I'm starting in the back pack and just happy to get round.
Give it a go & Good luck
