They will do this for 1 ride.....Then you will not get invited to go with them again. Better learn to not be afraid and ride a decent pace. Gravel varies all over the place and is nothing to fear. They go 140 mph on the Springfield mile.Out in the West here you might ride 140 miles of gravel and at 50 mph it will take a long time to finish your ride at even that pace. If you ride 30 instead of 50 you will be in the desert at dark and will be "that guy". Lost? Need a warmer jacket? Bike prep has a lot to do with it. You can sightsee at 50 just like you can at 30.
