Monsoon Cycles, Colorado Springs · Updated August 16, 2026

Our home circuit and the first map we ever built: a rolling 2km lap through a Front Range meadow of ponderosa, aspen, and rabbitbrush, with two hairpins and one honest kicker. Ride it right now, free, in your browser, on a smart trainer, a dumb trainer with a speed sensor, or just your arrow keys.

Every course carries a Prime Line sprint segment and, where the road climbs enough, a Summit Prime. Ride through the gold coin at a segment start for a powerup. Course records live on the in-game leaderboard, and reversed-direction laps keep their own boards.

Questions riders actually ask

Is Penny Circuit free to ride?

Yes. The whole of Gumwall Grand Prix is free, in the browser, with no download and no subscription. Sign in only if you want leaderboards, chat, and ride logging.

Do I need a smart trainer?

No. A smart trainer gives you gradient resistance, but a basic trainer plus a Bluetooth speed sensor works with estimated power, and demo mode needs nothing but a keyboard.

Is this the real circuit?

The centerline shape and elevations come from real open map data, so the corners and grades are where they are in life. The world around it, and the name, are ours: this page is an original Monsoon design, with no affiliation to or endorsement by any venue.
