i am also on day 5 - I think - too knackered to count 'em - and there is no way I could run anywhere. It takes all me effort to go to the shop for a Sunday paper and get back into bed to read it... And usually I work out for between 11/2 and 2 hours 5 times a week but I am shattered.
You - well - I'm gob-smacked. You ran 13 miles? you must have surgically inhanced remote control legs or something. you are super-human. Be proud. I'm in awe... In fact, you've exhausted me even to think of the prospect....
best wishes,
anya
