In reply to Zygoticgema:
There's a Duathlon event at Box Hill called the triandrun Winter Ballbuster, which involves running an 8 mile course then cycling 24 miles then running another 8 miles on a course up and down Box Hill. Reckon there might be a few people in need of remedial massage after that.
It's on the 7th November I think and should be in your area if you're a Craggyite.
