One clock. No reset.
STRENGTH → RUN → BURPEES + PULL-UPS. Start the clock immediately before beginning the scored strength portion. Complete all scored strength work, then the full run, then both finishing movements. Stop only when every required burpee and pull-up is complete. Lifting, loading, rest, transitions, walking and aid stops remain on one continuous clock. After the run, partition burpees and pull-ups however you choose. Official Time = Raw Time − Strength Credit. Lowest Official Time wins; equal Official Times share rank.
Make strength count.
