yes, do it... and tell us how you get along.
Me and a mate are planning on doing it at some point this year... but... are we up for it?
This weekend I've been in the saddle three days on the trot; 43miles sat, 37 miles sun, 20 miles today... all to fathom how I get along doing a lot more miles than usual day after day after day.
Saturday evening i was vary achy, Sunday's ride was fine, but knees starting to show signs of pressure, Sunday evening very achy, Monday's ride fine, but knees still showing signs of pressure... did get the train back rather than cycle (should have been a 35ish run), not because i was knackered (i wasn't), because i was sat in a beautiful beer garden, having a pint, enjoying the view, and figured "there's a train station just over there which will land within a stone's throw of home, so I'll have another pint"
what i've learnt is if/when i 'do it', I'd rather have a good night's sleep in a B&B than rough it camping, which makes the trip a lot more costly. I'm also wondering how my knees will stand up to 4, 5 or 6 day's worth of big rides... I really want to enjoy it, as opposed to 'endure' it.
but... Vernon is right, go for it!
