The other day I was going to meet up with some other runners in my half marathon training group (they are going to run the Powerade half marathon in Copenhagen on 9th September so I'm helping them get ready).
We were supposed to be running around 16k this time but it was so hot outside (yes Denmark does get hot too). Anyway I decided that a bit of variety was good for moral so we ran 4k down to the beach and took our trainers and socks off and ran 2k in the sea and wet sand! It was so refreshing :-)
We then ran the 4k back. We all agreed that this was great training and that we had all enjoyed it very much!
My plan for the next training is too run around about the 16k ending up at the beach and having a quick swim afterwards. That will be a great way to end a run I think :-)
