Hey, just seeing this. We had a local weekly TT series in Sacramento this year which was a lot of fun and a nice way to channel our racing energy during the pandemic. Basically, you need Strava, a Facebook group, and a couple cans of paint. The "Commissioner" would go out each week and lay out a course and create a segment on Strava. Someone would mark the start, finish, and any turns with paint, take a few photos, and post it to the Facebook group. Race day was Thursday and you could go anytime you wanted that day, up till 9pm so the Commissioner could tabulate the results. People would post on FB and heckle each other online.
A lot of the courses were on a paved canal path that everyone knows, but to mix it up, there were days where everyone had to go Merckx, hill climbs, gravel courses, and no-limit aero days. In addition to times, the Commissioner would award points for social media engagement (heckling each other on FB, basically), inventive or funny Strava titles, and just random bonus points.
Personally, it was one of the best things in my cycling life this year, especially since it was quality bonding time with my son.
