DD- the ultra I did was just a local 'Kent Challenge' one, but very enjoyable. I can only aspire to do something like Comrades in the future.
Minni - I'm just using a combination of the RW schedule, plus what's worked for me in the past (i.e. made it up), but I think i'll include some influences from P&D just because it all seems to make sense, even if I can't get the speeds yet.
I've used HR training in the past, more to slow down my long runs than anything else. Like others, I got bored of wearing the strap and the variation in the heart rate..but I still dust it off every so often. I got my max from a 10k I did (189bpm) and have never got close to it since. Shame.
!5m LSR for me this morning, found it quite tough....a combination of eating too late last night (after 9pm) and not enough fuel this morning (always used to have porridge, but the cupboard was bare apart from Shreddies). Lesson learnt, must try harder.
