How to split pace groups without splitting the club

Every club starts as one group. Eight people, one pace, everybody talks to everybody. Somewhere around twenty it stops working, and most clubs do not notice, because the people it stops working for do not complain. They just stop coming.

One pace for thirty runners means the fastest ten are holding back, the slowest ten are hanging on, and only the middle ten are having the run they wanted. Splitting into groups fixes that. Doing it badly creates three small clubs who share a parking lot.

Start from the people, not the paces

Do not pick paces out of a training book. Look at what your members actually run. If you have last month's check-ins, the split is usually obvious: there is a cluster around 4:50 a kilometer, a big one around 5:30, another around 6:15, and a handful of people who would rather run for two minutes and walk for one.

That gives you four groups, and the fourth one matters most. A walk-run group is the difference between a club that says all paces are welcome and a club where they are.

Letters, not labels

Call the groups A, B, C and W. Never fast, medium and slow, and never anything cute. Nobody wants to tell a coworker they run with the Turtles. A letter with a pace next to it is neutral, and it lets people move between groups without it meaning anything.

Print the pace as a number. "B · 5:30 /km" is a promise the lead has to keep.
Cap the popular group. If B fills at fourteen, the fifteenth person runs with A or C and discovers it is fine.
Let people choose when they say yes, not at the start line. Deciding in front of forty people is how everyone ends up in the wrong group.

Every group gets a lead and a sweeper

A pace group without a lead is a rumor. Someone has to hold the pace, call the turns and stop at the water fountain. And someone has to run at the back and count.

If you only have enough volunteers for some of the groups, staff them from the back forward. The fast group will find its way round. The walk-run group is where a new member decides whether your club is for them.

The pace of a group is the pace of its slowest runner on that day. A lead who cannot accept that should be running in the group above.

Start together, finish together

This is the part that keeps it one club. Everyone meets at the same pin at the same time. One person says the same thirty seconds to all of them: the route, the turn that people miss, where the coffee is. Then the groups leave a minute apart, slowest first.

Slowest first is not a courtesy. It means the fast groups pass the slow ones on the way round and say good morning, and it means everyone reaches the finish inside the same fifteen minutes. A club where group A has gone home before group W arrives is two clubs.

Check the split every season

Groups drift. The 5:30 group gets fitter over a summer and is running 5:15 by September, and the people who joined it in June are hanging on again. Look at the numbers in each group every couple of months. If one group is twice the size of its neighbors, that is where the next split goes.
