We’re fine-tuning an algorithm that computes estimated completion times for Zwift routes based on W/kg. It also computes an objective “Route Rating” from 0-100.
- The goal is to predict how long it would take a semi-experienced rider, riding efficiently in a group, to finish the course. Thus, the algorithm assumes you’re a 75kg, 183cm rider drafting on the flats, on a decently fast bike, and pushing harder on climbs than on flats and descents.
- You’re only seeing a subset of Zwift’s full route library because we have to add a bit of data to each route for the algorithm to work. This list will grow as we plug in these numbers.

Changelog
- Sept 13, 2024: input data for more routes, so the list continues to grow. Tweaked algorithm (now version 0.3) based on feedback from bot tests.
- Sept 12, 2024: initial public beta of algorithm version 0.2 released, with a limited set of routes.
- Sept 11, 2024: added support for point-to-point routes. Now factoring in time saved on descents. Refactored code so it can spit out results for 2, 3, 4W/kg as well as Route Rating (0-100).
