^ Not officially as the different routes have different start windows, but the 100 and 50 shared a fair bit of the route so if you were prepared to ignore official start times it would work for a good amount of the ride. However it would leave the people doing the 50 miler very lonely unless they took a long break and waited for others who started at the official time.
I guess if you could hold 25mph you could probably do the 100 and then catch up with the 50...
