Just over the River Thames near Radley Lakes there is the Culham Park Motocross Track, and there was racing this weekend.
The track loops up and down the hillside several times with a series of severe bumps on the bottom section near the river. The start is up a broader incline, allowing all the bikes to roar off together before reaching the hilltop and the first right hand turn.
Some of the down hill sections involve spectacular jumps
Before this race began, I saw a lots of stewards walking the track to ensure there were no obstacles on the dirt track. The bikes go at such speed – any object would be dangerous.
