You would really need heavy skill to do this but it must be loads of fun if you can do it.

Even in my younger more fit days, I would never have had the stones to do this.. Kudos!I've done a lot of those event's and the realy scary thing is you are not aloud to walk the track before hand, so on your first run you are blind as to what is coming !
But they are super fun events with a mix of trials , enduro and motor cross , but you need to be super fit .
