As of 02 July, halfway through the year. The black dashed line is the pace that finishes exactly on time; the faint dashed lines show where each person ends up at their recent pace. The flame counts weeks in a row with a session.

Hold each other accountable

Groups for friends, crews, boxes and clubs. A shared goal and a leaderboard everyone checks. Clubs approve who joins, and you choose what each friend sees.

Goals you choose

A million metres this year, 10,000 minutes of cardio, a sub-7 2k. With dates you pick, and the daily amount that gets you there.

Fair across machines

Row, ski or bike: time goals count every minute, and distance goals use Concept2's own challenge rule for the BikeErg.

Make it a race

Medals, gaps to the person ahead, a race inside every week, milestones, and a trophy cabinet for every goal you finish. Groups see progress only: never your single workouts.

This week's race

See your 2k get faster

Every 2k, 5k, 30 minutes and other standard piece you have rowed, with your personal best tracked over the season. Your season best and last season's, side by side.

Plus volume per week or month and pace over time, for each machine.

2k: time per attemptExample

Every interval, side by side

Work and rest kept apart, each interval against your average, and the fastest and slowest marked. Recorded with ErgData, every stroke is there to compare too.

#	Time	Pace	±avg	Watts	Rate	Rest

4 fastest	3:31.9	1:46.0	-0.9	294	27	-

Every stroke, with your heart rate

Recorded with ErgData, each stroke's pace, rate and heart rate sit on one shared axis, one line per interval, the first faintest and the last strongest. Point anywhere to read all three at that metre.
