Pedal Powered spacecraft story??

[Beowulf Shaeffer]

sorry to bother you with this, but I have been trying to track down a sci fi short story.  I think it is by Larry Niven, but my Google searches are coming up empty.  In the story there are spacecraft powered by pedaling.  The pedaling adds energy and accelerates the craft forward.  In a race, the 'cyclists' accelerate towards their goal, and then at halfway they turn around and accelerate in the direction opposite to their motion, so they stop at the finish line.

I just cannot seem to find the story, although I recall reading it at some point.  Any help would be appreciated.  I am a Physics professor and want to use this in the classroom.

It's not in Neutron Star... and I don't think it's in Tales of Known Space

Cheers

I think I might have found it.
Endurance Racer  by Phillip Nolte.

I only skimmed through it but it does have the inverse stop you wanted.  It was published in Quanta magazine in the December 1990 issue.

I hope this helps, also congratulations on your marathon run.

Thanks!  I just read Endurance Racer, and it is not the story I recall, but something like I had in my mind.  Cool story.

Maybe what I recall reading was some substory in a novel or something?
