Running

Incidentally, has anyone done one of the Regent's Park 10s before? My main concern is bike parking, not being sure of what locking facilities there are at the hub, or how many people will show up. Any help with that or other advice would be much appreciated.

I did a Regents Park 10k earlier this year. There is no bike parking at the Hub itself, but quite a few bike stands on the paths around it. The Hub has changing rooms and lockers for keeping your gear in, so very handy. It's a nice little 3 lap run in a great park. Enjoy!
