We did this because it was in our London Pass book. I may not have even thought of it otherwise. We'd hoped to do it on our first afternoon, but it was booked out, yet they kindly let us leave our small cases there while we explored a bit of London, and we booked into the 10.30am ride the next day. We're in our mid 50's, and I haven't done regular cycling for more than 10 years, but it didn't matter- we got around easily, and not even sore legs the next day. We had the wonderful Tanja as our guide, and can understand why she is getting good reviews. She's very entertaining, and informative. She's clear with the safety issues, and pays attention to where the end of the group is. We were only a group of 7, so we got through the tour easily. It's hard to describe what a buzz it is to cycle safely through London!! You stop at a few landmarks, and it also gives you an idea of what you want to go and see better later. This was a real highlight of our visit, and I think anyone would be delighted with their experience. Thanks, Tanja and the London Bicycle Tour Company! Wonderful memories.
