So I finished Week 3 run 2 this morning; both week 2 runs have gone ok and the basic running and breathing wasn't too bad and I generally felt quite positive about how I've improved - lack of gasping and aching legs is definitely good! The 3 min runs didn't kill me either. So overall I'm feeling really positive and pleased at how it's all going - those longer runs in a couple of weeks don't look so unachievable now!
However an hour or so after the run I noticed my right knee had got a bit sore, and it's felt worse through the day. Nothing really major but it just feels a bit "weak" I guess. Is the recommendation to perhaps take an extra rest day, keep it gentle, maybe try some ice on it or something? I was going to start swims tomorrow but perhaps I'll delay that a week. I don't want to drop too far behind the schedule but obviously don't want to do myself a serious injury.
I do have some quite steep ups and downs on my route, I cope with them ok in terms of the running but could they have aggravated the knee? It's on tarmac pavement around the estate. I have running shoes but they were cheapo (£11) bought over the net - I realise I need to get proper ones fitted in a shop but haven't had the chance to get into town to do that yet (plus I was holding off investing serious cash until I was sure I was going to stick with it...)
