I watched the women's omnium & men's sprint final today on the big screen at Potter's field, on the river near the town hall. It was a good atmosphere, and going to go down tomorrow eve as well - if I'm lucky and can get away from work early I will get there for 4.30/5ish to see the end of the women's omnium, men's keirin and women's sprint final.
The only issue is it could rain - though that will affect the spectators more than the riders
