A while back Track Addix had mentioned a 5 hour endurance at Hastings on Labor Day. Anything ever materialize?
I personally think it's a great idea, but the schematics of riding someone else's bike, how to compensate them and what happens if you go down is a bit much to overcome for most people. I think the best idea was a relay type race where you come in on your bike, then I go out on mine. Not really a true endurance race, but would probably have a higher turn-out.
I was curious myself... what is the official word? We'll have to ask Dean at Hallett
Here is some video footage of what an endurance race looks like. You almost always have a bike to chase and someone to almost hit!!
