May be I didn't make it clear enough for SilsoeSid?
Sorry, of course when you said...
The plan is for 45 teams of people to walk the entire South West Costal path in ONE DAY, that's 633 miles!
.... I should have realised you meant 45 teams will each walk different parts of the route and not the
entire route. There's me thinking it was going to be something like the 10 Tors where all the teams walk the (age grouped) distance.
Sorry to be negative, but to someonewho is way down the field, yet last year completed 26.2 miles in 5 hours
twice (London and Snowdon), 13.1 miles in just over 2 hours
4 times, not forgetting the multiple 15+ mile training runs, and then there's the 400m swim, 23km bike and 5 km run triathlon completed in 1.5 hrs,
...
...14 miles in 24 hours doesn't really seem to be that much of a challenge to anyone!
