I did my first race yesterday and enjoyed it. But I am a bit confused on the category system. I raced as a B and set off at the start to hold the front group, after a few minutes it didn’t ease up, they carried on riding at way over the B level. Looking at the web it looks like all groups start together so I was trying to hold onto the A group not the B group. How do I identify who I am racing? Don’t they have tops or stripes to match the group colour or something. Sorry if this is obvious but I can’t find an answer anywhere.
