About PaceLab

PaceLab is a free set of tools for runners, cyclists and triathletes. The workout builder turns plain-text intervals into a Garmin .FIT file you can import into Garmin Connect — so you can plan a session on a real keyboard instead of tapping it out on a watch.

Everything runs in your browser. Your workouts are never uploaded to a server. The pace, race-time and swim calculators are built for everyday training and race planning.

PaceLab is an independent project and is not affiliated with, endorsed by, or sponsored by Garmin Ltd.
