Thanks to @benwill for the link in an earlier post - I was umming and ahhing about which half marathon to sign up for to get me motivated again, and clicked on the link and had a look.
Then this weekend I went to a party in Bradford and met someone who I hadn't seen for 20 years or so, who happens to live in Eastbourne! So, an opportunity to see her again before another 20 years goes by - I have signed up, and we will go and spend the weekend by the sea.
Anybody else doing it?
