Nice move—good cause, good timing. Pacing is a rhythm, not a line on a map. Keep the route in thirds: first third easy, second for real pushes, last third finish strong. Logistics: set a clear handoff schedule, so no one’s stuck on a stretch alone. Bring a timing watch for each group and a whistle for cues. I’ll handle the timing, you sort the water stations, we stay sharp. You ready?
