Pretty worried about my next run tomorrow. Last run was two sets of 10mins with 3mins walking inbetween....found it quite hard. I wasn't too out of breath, but my legs just wanted to give up! Now I've read about the next run of 25 solid minutes...this seems like such a leap!!!!
Anybody else find this or did you find it surprisingly, not that bad??
How am I going to do this?! I'm scared!
