Our own code
The tools and page layouts are written for this site. The pages make no requests to other servers.
Formulas
The calculators use published formulas, implemented in our own code. Each one, with the paper it comes from, is listed on the methodology page. “VDOT” is a trademark of The Run SMART Project; we do not use the name, the VDOT tables or any published training plan.
