Your Million Dollar Idea for Today

deepfake

a route planning app where you input your desired walking/running distance (ex. 3 miles) and a region on a street map (ex. a 3 mile radius from your home address), and you get back a map of routes that are very close to that distance (ex. five laps around Oak Hill Cir. is 3.004 miles; the junction of West Rd. and Deer Glen Dr. is 2.997 miles from the junction of West Rd. and Hemlock Dr., etc.). you'd be able to specify the level of precision (ex. +/- 0.2%), the type of course (ex. circuit, direct a-to-b route), and the min/max elevation gain

routeloops is the closest thing I can find to this idea, but it only allows you to input one starting point at a time, and the route distances are often wildly different from your specification

^probably not an actual million dollar idea, as it would only appeal to a small population of obsessive assholes

i would pay for that!
