I think I may have got it! I need to slow down if I don't want to get injured. I will do my best but thanks for your guidance, especially the forthright stuff like that from TR. Sometimes I need things spelt out for me!
PMJ - you must have been young when you ran your first one. I was just 22 in 86 and I recollect that you are a year or two younger than me.
Dylan Man - made me laugh reading about your father & also think back to those times. I ran my first one in Paris and there were only about 4 or 5 drink stations serving cups of water (obviously). I don't think energy drinks had been invented. When I ran my PB in 1994 not much had changed. I sometimes wonder if I'm overthinking things but then remember I'm nearly 20 years older so need to be more careful.
Minni - I think that has been my problem with MLR's up to now. Wasn't sure of the point of them. However, I will follow the wisdom on here and accept P&D know what they are talking about and follow the plans as they are but remembering to listen to my body and take extra rest if it's needed.
I've been deliberately enthusing myself because I feel that this will be my last chance to make myself a decent runner again. However, there's a long way to go before my race day so I'd better temper it a little.
Thanks evceryone for your input/advice!
