Good on you for getting out and into it ;-)
7kms is not to be sneezed at, especially if you're coming down with a cold ;-)
i managed to get out yesterday as well and had the opposite problem to cold and damp - it was super hot and dry. I nearly ran out of water and decided to not go and run another 20kms. (that would have been silly)
But I did get to check out the course for my next ultra and it's not as bad as I thought it might be.
I just hope that it is a bit cooler when I do the hill climb on race day.
Glad to see you're keeping the running up and keeping motivated.
I needed a run. Will try to keep it up through the winter
