Relay Check Mark Calibration
In pairs, the outgoing runner finds the exact check mark distance so the baton can be passed at full speed inside the zone. Students work on reading speed, decision-making and relay teamwork.
How to play
- Pair up students of similar speed in lanes; each lane has a 20 m exchange zone marked with two cones, and the incoming runner starts 30 m before it (2 min).
- First estimate: the outgoing runner stands at the start of the zone, counts 6 foot lengths back and chalks a mark; the incoming runner holds the baton in the right hand (2 min).
- Test run: when the incoming runner hits the mark, the outgoing runner goes full speed without looking back; on the call "Stick!" the baton goes into the left hand (4 min).
- Adjust: if the incoming runner catches up in the first half of the zone, move the mark one foot length back; if they never reach the outgoing runner, move it one foot length closer. Six tries, then switch roles (6 min).
- Record: each outgoing runner measures their final mark with a measuring tape and the teacher writes it down (2 min).
- Final test: two handoffs timed by the neighboring pair, from the moment the baton enters the zone until it leaves (4 min).
Rules
- The outgoing runner never takes off looking back; trust the mark and the call.
- The handoff counts only if it happens inside the 20 m zone.
- After the handoff, both runners stay in their lane until they stop and then exit to the outside.
Variations
Easier
The outgoing runner starts at a jog and the mark starts at 4 foot lengths.
Standard
Check mark adjustment over six tries and a timed final test.
Harder
Calibrate the check mark on a curve, with the incoming runner running 40 m before the zone.
Adaptations
- Limited mobility: a student in a wheelchair is the incoming runner from 15 m or the observer who decides how to move the mark.
- Hard of hearing: replace the "Stick!" call with a light tap of the baton on the elbow.
- Lower fitness: pair with a classmate of similar speed so the adjustment is realistic.
Learning goals
- Adjust the check mark based on a partner's speed.
- Pass the baton inside the zone without slowing down.
- Work with a partner to make decisions based on what they observe.

Teacher tip
A common mistake is the outgoing runner leaving slowly to wait; they must go all out, and the mark is what gets fixed.
