I don't need a running jacket. I can run in the rain - my 3 running tops have not made it into the wash yet so I wore a cotton t-shirt. Had too much to drink last night so decided to do a bit of run walking this morning. Ended up doing 7.75k in an hour but I loved it. A no pressure run. Feet were soaked, mud all up my legs but I was really happy. The rain didn't bother me while I was running although I did feel a bit stupid on my warm down walk with the T-shirt clinging to me. Selfie showing my Mo (not long to go now before I can shave it off) and the effect of an hour in the rain.
