Having done level 1 in scorching heat last year and level 2 in the wettest of wet weather this year, I much preferred the wet!
I don’t know if it was down to the tyres or having more confidence, but either way they are incredible weekends.
I can only echo what everyone above has said, but one tip would be to not wear your Sunday best suit. I did, and although it was fine in the dry, where I just had to dust down my jacket, the wet weekend made a right mess of my suit. I washed it twice and still can’t get the coal marks off my jacket (gray Enduroguard). I ended up falling off in water crossings, managed to break my helmet, so again, don’t use a helmet that you cherish. Yes, it did it’s job, and you have to use a proper road approved helmet, but I shouldn’t have taken my £500 Tour X!
The instructors are absolutely brilliant, and make sure you are confident at a particular lesson before moving on to the next.
Definitely going back next year for the next level.
Cheers
Dave
