Just completed W2R3. Run 2 was a killer (for me!), so I wasn't looking forward to run 3. It was still hard but my legs weren't as heavy and the breathing was a little better (couldn't do Laura's tip - would need resuscitating). However, I don't feel ready to go onto week 3 - 3 minutes seems like such a big jump from 90 secs. I think I'll either repeat the whole week or individual runs depending on how I feel. Just wondering if it's worth looking at my footwear - shins ache a little. I also think I'll use the cross trainer in between runs.
