Finally sorted some accommodation in Earlsfield, London and although some people will say I should take more I think it makes sense* to only take 1 bike. Got a ss mtb, sscx and a geared road bike to choose from. Very close to the train station so could strike out to the mtb trails (in theory at least) and also keen to take part in cx races if I can find the time. That said I do love just knocking out some miles on the road bike. So which bike should I take? Cx bike is ahead by a whisker right now - can do cx races, put it on the turbo and also explore trails. I could also sling some gears on there if needed/wanted to.
*In that it's a small flat rather than one bike makes more sense than many
