JoPG, sorry to hear you're still having problems with your knee. In my experience, downhills are much harder on joints than uphills, so while you're still experiencing a bit of pain it might be advisable to seek out flat routes for your runs (if that's possible where you live).
Meant to say I have the Garmin 205, not 201 (I have the new version which has a much better GPS system and doesn't lose signal all the time like the older version apparently does). I deliberately didn't buy the 201 version because a friend has it and could never get a signal in London. As that's where I live, it would have been fairly pointless!
My 'proper' running kit is quite sparse too. I do have a decent pair of loose running shorts: really lightweight and dry instantly, and a Dri-Fit black t-shirt I bought for FLM. Other than that, most of my kit is courtesy of the Nike RunLondon 10K, which I've done 4 times - you get a proper, fitted t-shirt in your size and these are great! One year the race was in the dark (in November) with everyone in dayglo yellow long-sleeved thermal tops - that top has been invaluable for marathon training over the winter.
Pidge, best of luck with your half marathon on Sunday. I may not get online over the weekend as we have the in-laws coming to stay Friday-Sunday and it's out 2nd wedding anniversary on Monday, so will be a bit busy, but will check back as soon as I can!
