How do I increase registrations for a fun run?

To increase registrations for a fun run, put a price deadline in front of every registration window and personally invite last year’s runners back. In RunSignup’s 2025 RaceTrends data, 25.9% of all registrations arrived within 3 days before a price increase or registration close, while only 18.2% of 5K runners returned to the same race.

Rules of thumb (each one sourced, or arithmetic from the worked examples below):

• Expect the deadline spike. 25.9% of 2025 registrations came within 3 days before a price increase or registration close, up from 15.8% in 2021 (RunSignup RaceTrends 2025).
• Do not panic at 30 days out. On the 5K registration curve, a 600-runner target should have only about 229 runners (38%) in by then.
• 5Ks run few deadlines. The average 5K had 1.0 price increase in 2025, against 2.5 for triathlons (same report).
• Send two emails per deadline, 5 to 7 days and 1 to 2 days before it (RunSignup race director guide, 2026).
• Last year’s list is worth about 44 extra runners at the mid assumption band below, on a 600-runner target.

Why do fun run registrations bunch up around price deadlines?

Fun run registrations bunch up around price deadlines because runners can sign up at any time, so a rising price is often the only reason to act today rather than next week. RunSignup, which estimates its platform carries at least 50% of the US race registration market, counted 12.2 million participants across more than 97,000 events in its 2025 report. Its share of sign-ups made in the 3 days before a price rise or close has climbed every year since 2021, from 15.8% to 25.9%.

“Price increases are one of the most effective ways to drive action and get participants to take the final step in registration.”

Two cautions keep this honest. First, the 25.9% is a timing figure: it shows deadlines pull registrations forward, not that each extra deadline adds new runners. We found no public study measuring that incremental lift on 7 November 2026, so treat extra steps as a test. Second, the data is mostly US races priced in US dollars. The registration curve shape travels well; the prices may not.

Frequently asked questions

When should I open registration for a fun run?

Open registration for a 5K fun run about four months out with a priority window for past runners, but expect little volume early: only 4.4% of 5K registrations came more than 120 days out in 2025, and 62% of 5K runners registered within the last month (RunSignup RaceTrends 2025).

How many price increases should a 5K have?

The average 5K had 1.0 price increase in 2025, while triathlons averaged 2.5. The calendar above uses four steps so that every registration window has a deadline in front of it. No public study shows the extra steps add runners rather than move them earlier, so compare total registrations with last year before keeping all four.

Should I charge more on race day?

RunSignup’s 2025 report suggests adding a final price increase for race day registrations, and race day accounted for 3% of all registrations that year. Keep race day sign-up fast and mobile-friendly so the higher price is the only friction.

What share of fun run runners come back the next year?

Across all events, 17.2% of 2024 participants returned to the same event in 2025, and 18.2% for 5K and shorter events, counting only runners who repeated the same distance.

Does a referral programme work for a small fun run?

A referral programme often works at any size, because RunSignup attributes 5% to 7% of transactions to referrals when enabled and up to 15% to 20% when a race promotes it heavily. The difference between those figures is promotion, so mention the reward in the confirmation email and every reminder.

The Race Price-Step Calendar for a 600-runner 5K

The Race Price-Step Calendar maps a fun run’s expected registrations onto the published 5K sign-up curve, then places a price step and two reminder emails in front of each window. The shares below are RunSignup’s 2025 figures for 5K and shorter events; the 600-runner target and the prices are assumptions to replace with your own.

How to use it:

1. Set your target and multiply. Expected registrations in a window = target x that window’s share. For a 400-runner target, the 31-60 day window is 400 x 21.0% = 84.
2. Anchor prices to the market. RaceTrends 2025 gives the average 5K a minimum price of $28.49 and a maximum of $33.95. The $28 opening and $37 race-week prices above sit around that band; a charity fun run may sit lower.
3. Check pace at every deadline. Divide actual registrations by the cumulative pace target. If you are more than 15% behind (an assumption threshold, set your own), spend the next window on the reactivation sequence below before you spend on ads.
4. Keep it simple. RunSignup’s guide warns that if runners need fine print to work out how to save, the incentive loses its impact. Show the next deadline and price on the race page.

Longer events behave differently: 53% of marathoners registered more than 3 months out in 2025, against 62% of 5K runners registering within the last month. If your fun run has a half marathon option, run a separate calendar for it. For a high-ticket event, the discount maths in how much to discount early bird tickets is the better tool.

How do I get last year’s fun run runners to register again?

Last year’s fun run runners register again when they hear first, get a reason to commit early and are reminded at each deadline: by default only 18.2% of 5K participants returned in 2025. That figure counts only runners who repeated the same distance, so your true return rate may be a little higher if people switch distances.

The lapsed-runner reactivation sequence:

1. Within days of the race: thank-you email with results, photos, a feedback request and next year’s date (RunSignup’s guide calls the post-race moment the ideal time to plant the seed).
2. Before public opening: a priority registration window and loyalty price for returning runners only.
3. At each price step: the two calendar reminders, with returners segmented from new prospects.
4. Last 30 days: a personal text or phone call to previous finishers who have not re-registered, where you hold consent to contact them that way.

The return-rate and recovery bands are labelled assumptions: we found no public figure for how much a reactivation sequence lifts race repeats. Swap in your own list size and last year’s abandoned count from your registration platform. The list mechanics (segmenting, consent, cadence) are covered in more depth in how to run a database reactivation campaign.

How do I recover runners who started registering but did not finish?

Runners who start registering but do not finish are recovered with an automated incomplete-registration email, which RunSignup lists among the most valuable automations a race can switch on. RunSignup describes the recovery as “a meaningful portion” without publishing a rate, which is why the table above uses bands. Shorter forms help too: in 2025, 34% of registrants paid with Apple Pay or a saved card, and the report recommends limiting questions to cut drop-off.

Which channels bring new runners to a fun run?

New runners reach a fun run mainly through search, event calendars, email and friends: organic search drove 29.3% of race website traffic in 2025 and referral sources, mostly race calendars and timer websites, drove 25.1%.

• Referral rewards: 5% to 7% of transactions are attributed to referrals when enabled, and as much as 15% to 20% for races that invest heavily in promoting them (RaceTrends 2025).
• Teams: when teams are enabled, 29.8% of participants join one. Workplace and school teams are the natural fun run recruiters.
• Email: 12% of registration dollars came from emails sent through RunSignup in 2025.
• Club partners: a club member discount gives local running clubs a reason to share your race in their newsletters.

Measure each one with its own tracked link or coupon code, so next year’s budget follows registrations, not impressions. If you are filling a business event rather than a race, how to increase conference attendance covers the different buyer.

What does running this calendar yourself cost in time?

Running the Price-Step Calendar yourself costs mostly set-up time: four price steps, eight reminder emails and the reactivation sequence take an organiser roughly a day to build once on a platform with scheduled pricing and automated emails (our estimate, not a measured figure). The ongoing work is the pace check at each deadline and the personal follow-up to lapsed runners in the last month, which is the part volunteer committees most often skip. If that follow-up is the gap, an event marketing agency or a done-for-you calling and SMS service can run it; if your list is a few hundred names, doing it yourself is cheaper. When sales are already behind pace, start with what to do when event ticket sales are slow.
