Congratulations Frank! 25.16 km in one hour is fantastic!

Frank’s marathon time on his geared up 28" is excellent as well!
Maintaining 23.37 km/h for about 1 4/5 hour must have been really hard!

That is a 25.10 km/h average speed over 1:40:52 and 42.195km on a 24"!
There are no limitations on crank length for this marathon. I’ll guess
that the cranks used were 3.5 inches (89mm) or smaller.
