Hello All
have had a look at Essex MX website, and must admit, fitguy, it does look suspiciously like the location of the Essex Off Road Experience track location.
I had my one & only off-road biking experience here. At the time, there were 'alternatives' all the way around the track, you did not HAVE to take the jumps, humps, dips or hills unless you wanted to. By the end of the day I had managed (NOT mastered!) them all (with instructor help) and I am not brave, but I was determined to do the lot. So unless the new 'outfit' have changed the track around, I don't see any reason why beginners, or kids, would have problems coping. They also have a kid's track (which I don't remember) if you check out the website.
