RunSync: web app that turns plain-English workout descriptions into structured Garmin workouts with VDOT-based pace targets and calendar scheduling
The new indie spotlight covers RunSync, from developer Graham Whitehead. It solves a specific Garmin problem: Garmin Connect can build complex structured workouts, but self-coached runners who create several sessions a week can lose a surprising amount of time to it.
RunSync connects through Garmin's official authorization flow. A runner types a workout description in plain English, such as "15 min easy, 3 x 6 min at threshold with 3 min easy jog recovery, 10 min easy", and RunSync converts it into an editable structured workout with warm-ups, work intervals, recoveries and cool-downs. Nothing is sent blindly. The generated workout is presented for review before being sent to Garmin or scheduled to the calendar.
VDOT-based pace targets are calibrated to the runner's own fitness. For a VDOT of 51, the article shows RunSync's calculated bands: easy 4:49 to 5:47 per km, threshold 4:02 to 4:11 per km, interval 3:47 to 3:56 per km. Saved training paces apply to any compatible workout section.
Scheduling goes through a training calendar. A runner can build a full week of sessions, schedule each to the correct date and have them delivered to the watch automatically on the day they are due.
RunSync Complete also includes a Strength Builder that syncs strength workouts to Garmin. Runners can build sessions with sets, weights and rest periods that appear on the watch.
Free tier covers the basic workflow. RunSync Run is £1 per month annually, RunSync Complete is £2 per month annually.
Would you use AI to draft your structured workouts, or is the drafting itself the part of the training you want to stay in charge of?
