Well, that wasn't exactly fun. I did better than the last run (in total minutes, not in running one long piece), but still didn't manage to do the 25 minutes. I'm gutted.
I manged the 12,5 fine, turned around before the hill (the one I walked up last time and didn't continue running...) and ran back maybe a minute. Then I felt the stitch coming. I tried breathing in and out all the air, and it got worse. 20 meters further and I had to completely stop and bend over because it hurt so much. I never had a stitch in all those weeks till Week 7. Why now!? I don't think I'm breathing differently.
I walked for more than 10 minutes. Only started running again when Laura announced, that there's only 1 minute left. I ran for maybe four or five minutes before the stitch came backw. At least that's better than what I managed last time and gets this run up to 18 or something minutes running in total. No 25 minutes, but I'm getting there.
On Sunday I'll go back to my usual route. No hills, and maybe my body will no go "Oh she turned around, I can start getting the stitch in now!" this time. Wish me luck. I know I did 20 minutes and 25 minutes once. I can do it again! Someone only has to tell my body.
