But is there / should there, be a rule that novices can't participate in the trials?
No there isn't. But one trial isn't quite like any other. There's quite a few considerations here, not just simply safety. Light/heavy damage to bodywork is an obvious one.
Trial 1 was mainly narrow and tricky gates, different to 2 with steep cross slopes turns and plenty of tree obstacles confusing things and endangering bodywork, with 3 being quite extreme in climb angles and surfaces in a control/grip sense - very challenging, with a steep and slippery descent thrown in for good measure. 4, very tight turns on steep slopes and a couple of flags in 'very challenging' places!
If a novice is someone who hasn't driven off-road at all before, or in a syncro, some familiarisation would be a good idea before even T1, and sitting in with someone else going around a good idea too. Watching carefully beforehand is obviously good, and an experienced passenger onboard too. An off-road novice may have innate good car control and skills, or appalling ones that need correcting quickly. T2, T3 etc speak for themselves, not for the novice in my opinion.
Some factors:
Confidence in skills Vs misplaced overconfidence Vs lack of confidence
Natural caution; natural lack of caution;
Understanding and knowing your vehicle, its strengths and its limits;
Assessing the terrain, walking it if in doubt, assessing the nature and grip of surface, consequences of failure at any point and judging if its for you, in that vehicle, at that time;
Advice and help available, inc. recovery options.
Maybe a 'basic training' course for newcomers would be appreciated by all at syncro events, for everyones benefit.
I am sure we will have come to a decision to ensure at least a basic hour or so of induction is available to anyone who a) asks b) we think need it - at the next formal Syncronauts site event.
Additionally, I aim to ensure we have some general off-road driving techniques and syncro-specific guides written up by then, too. These can go a long way to dispelling myths and differing approaches to the same situation, before getting into that driving seat, but of course, only the real thing can hone those skills and as I said, watching others - the better and the worse.
