Segment Challenge was created by Ben Smith to host VC Venta's "Segment of the Month" competition for 2017. It replaces the manual spreadsheet tracking of each athlete's attempts at the Strava segments comprising the challenge.
The site is designed to allow any Strava club to host their own challenge. You can create a segment challenge for a cycling club, race team, group of friends, or local riders.
Strava segment challenges are a great way of encouraging people to go out and ride throughout the year, and to ride competitively. Even those who haven't yet tried racing or time-trials.
There's no cost involved if you choose to host your own competition. The site is completely free to use.
