Daren, sure you could do Hadrians wall 67-69 miles. Just run it as 5 halfs? Simples. You peg each one, we catch you up.
DD, nice 5 miles, in km markers? Not sure what you mean about older & slower. You're plenty fast. Think you meant wiser.
Ant - go for it. Get that sub 20 PB in 2012
Brol, Thunder Run - our 2 teams are pretty crammed with OHs already if everyone returns plus other friends, but Mr Zuvai and a few others could squeeze in. kcs already interested a few pages back.
Mr Zuvai, its for fun, not race. Minni If its a competitive team ideally you camp close to start line for fast change overs. We were a 10 minute walk away, furthest!
2old, how do I recover? good question, still working on the answer
Think the circuits, S&C help, but i carefully watch my energy levels, my training probably not that different to Daren - but with marathons. Haven't used by HRM for ages, but have this week to gauge things.
Did I mention the top field 10k at end of December I have entered? Last year top 28 all under 31 minutes, top 60 people under 33 minutes - Brownlee brother raced but 2nd. Fast! Winner Jonny Mellor I've done running bootcamps with - did it in 29.10. Got to be some running to get that sub 40 10k 
Who is racing this weekend?
