Staring line/run-ups...

While the race distance is a known fact, how does one find out just how long the run-up is for any given race?
I would think that could/would play a big factor in many race finishes that ended in a photo or close call.

It is usually given in the DRF on with the Racetrack details.

Or it can be found on a horse’s chart.

On this chart of the Pegasus World cup you will see it on the 3rd line below Fractional Times. Run up 60 feet.

I assume I can direct link
