What's a decent distance for weeks 2 and 3? I've just measured the way I went this morning (including warm up and down) for the whole of W2R3, and I got to 3.8km. Does that sound about right? I'm not really measuring anything else - speed, heart rate, etc. Just going to half way and turning round. I know it's about the long haul, but I'm interested to know if I'm on track for 5K at W9 or not.
