maybe you should revise your marathon pace - 5.23 would give you a pretty good marathon time!
Don't think 2.21 is quite within my capabilities!
I'll be watching your progress on the net as it'll be too depressing to go there and watch.
Good luck and what time are you aiming for?
how far under 2:40 are you aiming then?? Good luck!
Thanks! I'm aiming for something around 2.40, that's what I'm going to pace it for.
All the best Mike - stick to the plan and it'll all go well!
Hope you smash it, best of luck!
