Good to see you have recovered Lazurus style Chick.
Glad to see you are making a post injury come back as well BeDe
Oh by the way how important is it to warm up as i've never done it and recently have been feeling a slight pull in my hamstring ? am i being stupid ?.
In short, yes you are. Although Chick gives a polite description, I would say that you don't jump into bed with the love of your life and bang away like a teenager on heat. We all need a little foreplay to warm things up and get the best out of every 'session'. If you don't lubricate yourself properly with a warm-up then you will get hurt!
20m for me on Sunday exploring new off road routes in the snow, then work closed on Monday, so I fitted in another 2hr 16m run. Tonight I've got 14m inc 7m @ 85% (Marathon HR). I just hope I can find enough snow free ground to maintain the effort!
edit: Forgot to say - great questions from Neil (welcome) and equally great answers from Brian (as always).
