Is there anything to stop one rider flipping a wheelie into an oncoming rider, such as a barrier that seperates the two lanes?
No barrier. Every loop of the runway takes about 10 minutes You go up one side about 2 metres in from the edge of the grass. In that ten minutes you are at the least 20 metres (entire width of the runway) away from the 4 other bikes coming down the other side of the runway on four occassions as they pass either going up or down.
Is there a minimum distance between riders on the same lane to stop one rider wheelieing into the rider in front if that rider crashes?
Nope, not that I recall, though you tend to spread right out automatically, most of the day we were all at least half a mile apart as we were going down the runway and back up
If there are four riders all practising at the same time I assume there are numerous instructors rather than just the one?
5 riders. Nope just the one. Jimmy would ride up the runway and peel off and side behind you (no mirrors on bikes so you couldnt see him) and he would watch you 3-4 attempts then stop you and advise you on what to do etc, and then move onto the next person. Half the time you don't know he's watching you, the other half you do. The one instructor in the morning was fine since we were all trying the same thing at the same level, but in the afternoon he left us to continually practice going up and down only coming out every so often, but we thought we could have done with a bit more support/instruction at that point.
Oh, and no ulterior motives for the questions (as I've recommended Jimmy's school numerous times as he's the only other school that's run by a pro stunter), I'm just genuinely curious how he runs his days
The only thing that pissed me off was some of his family and some of his mates turning up at lunchtime and took up all the seating and watching us.....also so we had to stand beside the bikes for a rest/fag every couple of laps cause they were taken up. I'm there to practice wheelies,
not practice wheelies in front of a crowd...If I did it again I think I would specifically ask if anyone's going to turn up and watch or not, and if they are, book somewhere else!
