1,000,000m club charity challenge question

[team2bfit]

Hi all, we are a gym looking at running a fundraising 1,000,000m for McMillan cancer research later this month. The idea is to get our members to come down over the course of the day and row whatever distance they can on one of our 10 rowers (all model D's with PM3/4's) We were wondering if there is any way of linking the rowers together that would show the accumulative amount of meters elapsed or remaining? The only software we have used is the Venue race application which doesn't support this feature.

Apologies if this is in the wrong section
