That is my only conclusion from my run Wednesday, which wasn't too good. It was windy and warm and I set out on a solo, easy recovery run. But immediately my stomach protested, so I got through 2 miles and then bagged it. Oh well!
Today I'm giving running a rest and hopping on the bike. It's raining all day I think, so it will just be an easy trainer day. Perhaps some Spinflixing is in order.
