About this race
River to River Runners - Prediction Runs
What is a Prediction Run?
A prediction run is entirely different from other races that you’ve run in the past. Rather than finishing first or running the fastest, the object of a prediction run is to finish as close to your predicted time as possible.
Can I use any sort of electronic device (i.e. watch, heart rate monitor, sundial, car, etc)?
No, that would make it much too easy.
No watches allowed!
How long is the course?
You won’t find out till you get there! Usually between 2.5 miles and 4.5 miles.
How much does it cost?
$1….Probably the cheapest race you will ever run.
How do I get involved?
Just show up. The race times and locations are listed below and on our events page. The races are open to members and non-members. However club members earn points at each race for a chance to win some money at the Annual River to River Runners Banquet held in January.
