What a sweeper actually does

Most of the mail we get from run leads is about the front of the run: routes, start times, how to cap a group. The mail that worries us is about the back. A runner who took a wrong turn. A first-timer nobody saw finish. A lead who counted thirty-one at the start and thirty at the coffee shop and spent an hour driving the route.

Every one of those is a sweeping problem, and in nearly every case the club had a sweeper. What it did not have was a description of the job.

The job, in one sentence

The sweeper is the last person in the group, the whole way round, and does not go home until everyone on their list has.

That is all of it. Everything below is how.

Before the start

1. Read your list. A sweeper is responsible for one pace group, not the club. Twelve names, not eighty.
2. Find the new people. They are marked. Say hello now, so they know who you are when it matters.
3. Check in with your lead. Agree where the group regathers. On most loops that is the turn people miss and the top of the hill.

On the route

Stay behind the last runner. Not beside the second-to-last runner, chatting. Behind the last one. If someone stops to tie a shoe, you stop. If someone walks the hill, you walk the hill.

This is harder than it sounds for anyone who is a stronger runner than the group, which a sweeper usually is. The instinct is to drift forward to where the conversation is. Do not. The runner at the back knows exactly how far behind they are, and a sweeper who keeps glancing ahead tells them they are a problem.

Run as if this is the pace you came out for. For this hour, it is.

If a runner needs to stop altogether, you stay with them and tell the lead. The check-in list will show the group as one short, and the lead will know why.

At the finish

Check everyone off as they arrive. This is the step that gets skipped, because the finish is noisy and people scatter toward coffee. The list is not clear until every name on it is checked in or accounted for, and a sweeper with one name unticked does not leave.

On the app this is the screen that says 11 of 12 in with the missing name underneath. On paper it is a pencil. Either works. Memory does not.

What it is not

A sweeper is not a coach, and not a medic, and not responsible for anyone's pace but their own. They carry a phone and the lead's number. Some clubs give them a small kit: a foil blanket, a few bandages, a spare pair of gloves in winter.

They are also not the same person every week. The clubs that sweep well have a rota of six or more, and a rule that every lead sweeps once a season. Nothing teaches you how to lead a group like watching it from the back.

Thanking them

Sweepers finish last, which means they arrive at the coffee after the table has filled and the first round of stories is over. The clubs that keep their sweepers make a point of the opposite: a seat held, a coffee already ordered, the sweeper named first in the recap. It costs nothing and it is the reason the rota stays at six instead of shrinking to one tired volunteer.
