I'd love to keep posting etc and swapping notes on progress, although I'm right back at square one - still after nearly 6 months off, I'm just so pleased to be able to get back out.
You could start a 4:15 thread - people might not necessarily think to look on here if they feel that it's only about Paris - but regulars will know where you are
I do use my Garmin for reps, it's more that it's quite busy where I run, making it difficult to find the space to do reps without either bumping into people, or having to slow down etc to avoid them / traffic. The short ones advocated in some programmes would be quite difficult, so I've tended to do mine as longer ones, ie in mile distances to avoid the crowds. There are a good few hills near me which I used to use for hill reps, but again, there are a lot of people going up and down, so it wasn't terribly successful. I'm going to check local routes out and see if I can find some spots which would do for shorter reps.
