Fairly newish to road cycling, can manage around 13 miles an hour over 15 miles. I'm tempted to enter a local charity event next week which have several distances the smallest being 25 miles which I think is achievable. I've done loads of running events so know the set up but never a bike one. Just wondered what to expect and what will I need?! There's not much info on the site, looking at the pictures people tie numbers to their handle bars do people normally go prepared with cable Ties?! I don't have a bike lock tho figured using the toilet it would be safe at the start finish?! I'm so nervous and unsure. I'd love to have a go it does seem quite a relaxed event judging the website and more a charity fundraiser but still!
