A village club wants to know how to organize a trail race with volunteers rather than a professional crew. The sequence is route first, authorisation second, then insurance, safety cover and course marking.
Quick answer: fix the route, secure landowner and local agreement, obtain the sports federation’s opinion, declare the event to the mayor or prefect, insure the organisation, then mark and staff the course. Move up to the prefect whenever the course crosses several communes.
Wider context on formats and calendars sits in the outdoor running events hub. The rest of this guide takes a first-time race director through the steps in the order they unlock each other.
Fix the route and the scale first
A trail race starts as a line on a map, and nearly every later decision depends on that line. Settle it before approaching any authority, because the declaration dossier asks for the route plan, the date and times, the estimated number of entrants, the planned safety measures and the race rules.
- Walk the course. Note surface types, junctions, road crossings and places where runners could take a wrong turn.
- Draft staffing from the notes. The same guide recommends planning provisions and volunteer staffing from your course notes, so junctions and crossings you flagged become posts to fill.
- Estimate entrants. Choose a ceiling you can staff and insure. The authorities will ask for the figure.
Permit complexity and cost are a recognised challenge for trail races, as discussed in a Race Directors HQ podcast episode on trail and ultra races. That is a reason to start the administrative steps early rather than leave them until the course is perfect.
Agree the route with landowners and local authorities
Landowners and local authorities decide whether the route you drew can actually be used. Approach them before you place any marking, not after.
Race Directors HQ advises getting local authority, police and landowner agreement before marking, and says that if the marking needs private access permission, landlord consent should be in hand before you begin. A short written agreement per landowner is a sensible way to keep that consent on record. Ask each owner what they want to protect, such as livestock, crops or a particular path. Fold their answers into the route rather than treating them as obstacles.
Expect the authorities to have a say beyond your own plan. According to the local authority guidance on running a race on public roads, the mayor or prefect may order additional safety measures. The organiser must also restore public roads and their verges after the event, so budget volunteer time for clearing up.
Declare the race to the right authority
In France a race on public roads or paths is declared, and the recipient depends on where the course runs. Check with your town hall or prefecture whether your specific trail sections fall under this procedure, since the guidance quoted here concerns races on the public highway.
Single commune or several
For the general case of one commune, the declaration goes to the mayor. If the event crosses several communes within the same department, it goes to the prefect instead. A route that wanders over a commune boundary therefore changes who you deal with, so confirm the boundaries on your map early.
Federation opinion before filing
The same guidance says the event is subject to the opinion of the delegated sports federation, and that opinion must be obtained before the declaration dossier is filed. The federation has one month to reply, and silence after that month counts as a favourable opinion. Build that month into your calendar rather than relying on silence, since a reply may raise points you want to address in the dossier. If your club is not already affiliated, ask the federation how to submit your event.
Filing the dossier
Prepare the five dossier elements named earlier. The safety section lists marking, stewards and rescue arrangements, so it needs real answers from your staffing plan. Competitions with more than 100 participants have a separate section of rules in the guidance, so read it if your entry cap approaches that size.
Insurance and volunteers
Insurance is mandatory for the organiser. The local authority guidance requires a civil liability policy that covers the organiser, the people helping to run the event and the participants. When asking an insurer for a quote, confirm in writing that all three groups are named, because volunteers are part of what the guidance expects the policy to cover.
There is no fixed volunteer headcount in the guidance. The practical method is the one from the marking guide: let your course notes decide. Each junction, road crossing, aid point and start or finish function becomes a post, and posts become volunteers. Add reserves for the posts where a no-show would leave runners unsupervised. Brief every volunteer on their post and on who to call if something goes wrong.
First aid and emergency cover
First aid belongs in the plan from the start because the declaration dossier asks about it directly. The safety measures it lists include marking, stewards and rescue, so the authorities will expect to see how an injured runner would be reached and helped.
- Ask the authority what it requires. Because the mayor or prefect can order measures beyond your plan, put your proposed cover to the town hall or prefecture early and adjust before the dossier is final.
- Match cover to the course. Mark on your map where vehicles can and cannot reach, and tell every post which access point is nearest.
- Brief the stewards. Everyone on the course should know the emergency contact and the meeting point for responders.
Food, water and support points carry their own safety role. The companion guide on how to run a trail race aid station covers staffing and set-up for those stops.
Course marking
Marking is the most visible safety measure runners will rely on, so test it rather than assume it works. Race Directors HQ suggests testing marking materials a few days apart, revisiting the marks to see how they degrade before buying large batches.
- Choose materials for the terrain. Different surfaces take different marks, which is why the earlier timing exercise by terrain type matters.
- Mark late enough. Spray chalk dissipates naturally 10-20 days after application, so apply it close to race day rather than weeks ahead.
- Use reflective tape for night sections. The marking guide recommends reflective red-on-silver barrier tape. The night segment runs from the point where dusk will catch the slowest runner to the point where dawn reaches the fastest.
Keep the marking consent from the landowner stage on hand. If a mark disturbs a field or private track beyond what was agreed, the relationship you built earlier is the first thing at risk.
The final stretch and race day
Once permissions and cover are settled, the work becomes logistical. Confirm volunteers by post, verify the marking along the entire course, and walk the start and finish area with the team who will build it. A written list of tasks per person prevents gaps. The trail race organizer checklist turns these tasks into a tick-off list you can print for the team.
Publishing the course in advance helps entrants arrive prepared. A route uploaded from a GPX file is all that Trail Run Project’s race-sharing page asks for in addition to a few photos, and the service is free to use.
After the event, clear marking, restore any road edges and thank landowners promptly. This is what keeps agreements in place for the next edition.
When to pause or escalate
Some situations call for stopping and re-planning rather than pressing on.
- A landowner refuses or withdraws. Reroute and re-confirm before marking anything, because the route in your dossier must match the one you run.
- The route crosses a commune boundary. The declaration then goes to the prefect, not the mayor, so redirect your filing.
- The entry cap grows past 100. Read the separate rules for larger competitions before accepting more entries.
- The authority orders extra measures. Adjust staffing and cover to match, and do not open registration until the plan satisfies them.
Checkpoint table
| Stage | Who is involved | What happens | Planning use |
|---|---|---|---|
| Route and consent | Landowners, local authority | Agreement is secured before marking | Do this first; later steps depend on the route |
| Federation opinion | Delegated sports federation | Reply due within one month; silence counts as favourable | Leave the month free before filing |
| Declaration | Mayor (one commune) or prefect (several communes, same department) | Dossier with route plan, date and times, entrants, safety measures, rules | Check boundaries to know where to file |
| Insurance | Insurer | Civil liability for organiser, helpers and participants | Confirm all three groups are named |
| Larger events | Authorities | Separate rules for more than 100 participants | Check before raising the entry cap |
These stages follow the local authority guidance on organising a race on public roads.
Frequently asked questions
Can the declaration be filed online?
Yes. The guidance says the procedure can be done online through the sports ministry’s declaration platform, or by post using the form.
Who pays for stewards ordered by the authorities?
The organiser. If the authorities order a stewarding service for the event, the guidance states that the organiser bears the financial cost.
How long does spray chalk last on a trail?
Race Directors HQ says it fades naturally 10-20 days after application, so it suits marking close to race day rather than far ahead.
Is there a free way to share the course with entrants?
Trail Run Project lets organisers share a race by uploading a GPX file of the course with a few photos, and it is free to use.
