Pick a scoring rule that isn't step-count
Pure step counts reward whoever walks to work and ignore lifting, cycling and swimming entirely. They also invite the phone-on-the-dog problem.
Score consistency instead: reward the number of active days first, then minutes, then variety. That way a 20-minute session on five days beats one heroic weekend, and people with different training styles can compete on level terms.
Keep it weekly
A month-long challenge is decided in week one and ignored in weeks three and four. Weekly cycles give everyone a fresh start every Monday and keep the bottom half of the table engaged.
Propal's leaderboard already runs on weekly resets with a live countdown, so the structure is built in rather than tracked in a spreadsheet.
Scope the table so it feels winnable
A single company-wide table with hundreds of people demotivates everyone outside the top ten. Scope by team, role or city, and run squads so people compete inside a group they recognise.
Handle mixed fitness levels
Score effort, not performance. Because Propal weights turning up over output and caps single-day contributions, someone starting from zero can score well by being consistent — which is the behaviour you want the challenge to produce anyway.
Make participation voluntary and private by default
Health data at work needs care. Everything visible on a Propal profile is opt-in per field — activity, weekly standing, location, company — and anyone can leave the public view without leaving the app.
Set up in an afternoon
Have people create accounts, connect Strava if they use it, and join a squad. From there, the weekly table, countdown and challenge tracking run themselves.
