Strava Spoofer is a feature in CycleBike+ that simulates a ride at one of more than a dozen famous Velodromes all over the world. For example, here is a "ride" I did at the Hellyer Park velodrome in San Jose, California.
Strava Spoofer uses a speed sensor and some mathematics to calculate the position you would be at if you were riding at a velodrome. Other sensor data like heart rate, power and cadence are also recorded if you have those sensors. This ride can then be uploaded to Strava, Ride with GPS, MapMyRide, or other fitness sites like Training Peaks. Usually the GPS receiver in a smart phone gives the position recorded for your ride. Other expensive cycle trainers like Zwift or Trainer Road also simulate your location as you ride.
How does Strava Spoofer work? I've analyzed the tracks of a number of famous velodromes around the world and calculated the center coordinates, tilt, and major and minor axes. Every second you're pedaling on your trainer at home, your position around the track is calculated based on your speed using an approximation to the incomplete elliptical integral of the track parameters. (What???)
Choose a velodrome under ANT+ Settings Menu >> Trainer Mode (Strava Spoofer) in the CycleBike+ app. Enjoy your "ride"!
