Set out for W7R1 today but it didn't go to plan. Managed the first 9 minutes but was struggling with my breathing. I had to slow down to cross over a road and couldn't get started again. Walked for a bit as the next part of my route was uphill and started to run again when it was flat but didn't manage to get far before I got a stitch in my right shoulder so started walking again. Alternated walking and running for a while as it was still having to go uphill occasionally and I couldn't shake off the stitch. Eventually the stitch went and for the last 5 minutes I managed to run again (all flat or downhill from this point). So not a great day at all. My legs feel really heavy now so will take it easy, have a rest day tomorrow and then try again. I've come this far, its no time to give up.
