I was thinking about playing a round of golf on Sunday after my long run (12miles). Is this wise. I'm not too concerned if my running affects my golf but am concerned about injury as running HM at beginning of September.

Opinions please

sounds like a good way to warm down to me.

I used to play golf after running and it produced better rounds...don't know why. Possibly due to fact that I was physically tired and therefore played golf slower than usual and/or was more relaxed about the round.
Still played military golf though!

I can assure you it didn't improve my golf on that day. Military golf is the only kind I know!

The hot summer was rotten for my running but my drives went miles...well they rolled for miles on the scorched earth until they found the first cut that is!

played golf on a hilly course yesterday and ran 10k race today. It certainly resulted in a tough end to the race today!
