Thanks MP - I agree I have to be careful not to burnout - fatigue usually stops me before my brain does. I'm almost sorry I started running this spring because I didn't expect I was going to enjoy it quite so much

My weekend rides are usually about 40 km but we do throw in the odd 50-80 km ride every 3 weeks or so. Last year we did 2 metrics in the June/July so I will make sure we build up to that again carefully. I an gungho to do a loop around the lake that's about 160km (a full century).

I guess I should look at some of the Tri training stuff and see how they fit it in.
