Kelvin the tour guide was very knowledgeable and the pace was easy going. Shame Washington was on lock down so couldn't get into any of the museums or close to monuments!
What a great way to be introduced to this elegant city. Thoroughly recommended.
Our guide (Andy) was outstanding. You don't need to be an athlete to do this, but this could be rough if you are out of shape and the weather is hot. Having stated that this was a pleasant tour. Do it in the morning; less crowded on the streets after morning work traffic dies down and before pm traffic starts. A full 3-hour treatment covering a lot of ground and stories. They do a good job in setting you up with nice bikes and helmets (we brought our own, but it would have been fine to use theirs - at no extra charge). We got this on "sale" but this would have been worth the regular price.
