So after the stitch disaster in W6R3, I went straight onto W7R1 this morning, as it's much the same anyway.. and did it without a problem!
Although the temp was still low it didn't feel as cold despite the snow coming down which I was running face into for the last 10 mins.. Had a slight niggling stitch at times but concentrated on deep breathing and that seemed to help. I felt more focused this morning and able to concentrate on my nice, slow pace and breathing better.
25 min run done, for an asthmatic who could never run before, I find that amazing progress in 6-7 weeks.
