Chronolio for Race & Endurance Event Directors
Race day is a schedule wearing running shoes: staggered wave starts, aid station windows, a road closure with a hard reopen time, and a course crew made almost entirely of volunteers. Chronolio keeps it all in sync.
The job, as it actually is
Wave starts cascade through the whole day
Staggered corrals, a road closure with a fixed reopen time, and course sweep are all linked — one delayed wave pushes the closure clock and the finish-line teardown right along with it, on a permit the city will not extend.
Your course crew is volunteers with a two-hour window
Aid station captains, marshals, and sweep vehicle drivers need one clear instruction — exactly when their job starts and ends — not the whole race-day operations plan, most of which doesn't apply to their post at all.
Weather can rewrite the day mid-morning
A heat delay or lightning hold reshuffles start times, aid station staffing, and the awards ceremony all at once — and every minute that information doesn't reach the course is added risk for runners already out there.
Where Chronolio fits your workflow
The whole day, cascading correctly
Packet pickup, wave starts, aid stations, road closure, and awards all live on one timeline — delay a wave and the reopen and teardown times recalculate with it, instead of you doing that math by hand at the finish line.
Learn more about Bulk Editing & Assignment →Marshals see one job, not the whole race
Assign volunteers to their aid station or marshal slot and share the live link — each sees exactly their window on their own phone, no radio call required, and no morning briefing sheet to lose in a pocket.
Learn more about Contact & Vendor Management →A weather delay reaches everyone at once
Shift the affected blocks and every volunteer with the link sees the new plan immediately — revised start, aid station times, and awards slot, all in sync, without a single radio call across the whole course.

Save the race-day structure and regenerate it each season with new dates, waves, and volunteer assignments in minutes instead of rebuilding from scratch every year with a different set of organizers.

Can I schedule staggered wave starts and the road closure together?
Yes — build waves as sequential blocks and the road closure as a duration that follows them, so a delayed wave recalculates the reopen time automatically.
How do volunteers know their exact shift on race day?
Assign each volunteer to their aid station or marshal post and share the live link — they see their own window clearly without needing the full race-day plan.
Can I reuse the race-day schedule for next season?
Yes — save it as a template and adjust dates, waves, and volunteer assignments each year instead of rebuilding the whole operations plan.
