Hello I'm back after my Easter silence! I'm still running - on a good day I can now do my 5k in just over 29m, and I have on a couple of rare occasions pushed the distance to 5.7 or even 6k.
Kasterborous and MadMonkeys yay so close! Well done! And then you just keep going on and on and on! And MadMonkeys have you tried running with your cold? If it's "only" a head-cold rather than full blown aches and shivers I mean! I have been running with a bad cold all through the holidays and really i made no difference, except me not wanting to go out - I was fine once I started, though on occasion my breathing must have sounded even worse than usual.
Hmm it would appear I have bread more runners! While I dragged my 9-year old DD round for 1M of Sport relief (and she raised £147), it's my 6-year old DD who amazed us all last week when she ran (voluntarily, we actually tried to dissuade her at first) a loop round the park, without stopping, and that was (I measured afterwards!) just under a km (0.8). And after a short break she did it it again, no stopping! I had already run that morning so I was not inclined to join her but we might do something next weekend - though that means 7 boring loops round this park for me 
MaryShelley don't beat yourself up. I would probably go back the previous week to build a bit more stamina and then try again. There were some weeks that I did again and again before moving on. The thing is you really really CAN do this. But as you found, your head needs to be on board
. Give yourself time. And if you need to walk, then do, and then run a bit more. It still counts, don't be defeated if you don't manage to run the 20m in one go at the first attempt. The total running time also counts! And you will have done a lot more than 20m overall in one run by now. We all have good days and bad days - I have been running for coming up to 3 years now, and am just inching back to covering the 5k in under 30mins, but yesterday for some reason my legs really ached so I called it a day after 25 mins / 4k.
