Hi Mark, I did my level 1 at Rockingham on the 7th of july this year and it was heavy rain most of the day, I think we got one dry session all day but in the classroom Andy Ibbot said he loves riding in the rain and my instructor told me that the rain is good as it slows everyone down giving more time to concentrate on the drills. I think if you intend to eventually do all 4 levels you have no need to repeat level 1 at this stage as I believe that in level 4 they make up a training package focusing on your weak points from the previous 3 levels. Also you mention that you never got to cover body position but this is covered in level 3,
Do you still have the little level 1 drill booklet you got at the school, this lists the drills for the day and I think that all of them would benefit riding in the wet, also it is worth investing in both of the twist of the wrist books,
I am not an expert but I would say do all of the levels first then if you feel the need go back and repeat specific levels!
Thanks for the reply - I'm basically going to do as you suggest and will be booking for next year. Got both books too and will be practicing as much as possible before the next school day.
Cheers,
Mark
