Newbie seeks advice!
Hi all, am a newbie signing up for my first super sprint tri, baby steps! My question is (please don't laugh) do I need to invest masses in a racing bike yet? I just want to do one tri and see if I like it, I can do 10k on my bike but it's an old mountain bike. Will I look like I turned up to Ascot on a donkey? Or is it common for newbies to have a go on an old bike first? Many thanks!
