I ran in my back up trousers today and it was a disaster. I haven't worn them for a few weeks and they don't have a pull cord but have developed a problem. I had to keep stopping every few minutes to pull them up otherwise I would have been showing my pants to passing drivers.
On the plus side new running belt worked much better than the arm band I'd been using for my phone previously. Felt a bit naked without Mr S and forgot to start running (suddenly realised I was further down the road than normal). Back to Mr S for the next run I think!
