Hey from Scotland!!

Basically when I started I split my run into 3, so started with 5 mins on treadmill to warm up, 5 mins on the road and finished with a 5 min cool down on the treadmill. Seemed to work ok. Hope that helps.

Next year would be fine for me, whenever you feel up to it!

Wow - Tough Mudder, eh? I'd heard of those events and always hid behind the sofa! It makes the puny road races I have planned look pretty lame, so you have my respect. One event that appeals (and might just be do-able in minimalist shoes) is the LAMM - ever thought of doing that? The John Muir Way sounds like a good option for a fully BF challenge though.

Please do give me a shout when you're next in the museum, it would be good to meet! I curate the vertebrate fossils (everything from fish, amphibians, reptiles including dinosaurs and birds, and of course mammals, not that we have many of the latter three).
