Yes, #1T, I did the Spring Cycle yesterday with my 7yo son on his BMX. I thought it would be fun to go over the bridge with him and see how far he could go. Unbelievably, he did the whole thing, all 50km, in about 4hr45. Super impressed. I think he's broken the bike though - some bad noises eminating from the rear hub by the end. May be forced to by him a bike with gears after that effort. It's a great ride and the weather was perfect.
