The course at Aldersley Stadium is more technical than most, so you should have an advantage against the clueless roadie types. This being the case though, you really need to hammer it on the “in between technical sections” to keep your place.
It’s an interesting course so just enjoy it. It’s your first one so no-one’s expecting anything. I was seriously into my racing last year, but now I just race them for fun. I enjoy myself, ride as fast as I can, and if I beat some people in the process then great.
I might be there, but will probably enjoy a clubrun more, so may do that. I don’t think the WMCCL guys will care if you have a drink tbh and there are no specific pits there, but most congregate around the finish line.
Have fun, Rob
