The Demographic Trends Redefining Endurance: Data Driven Report

Key Trends Reshaping Endurance Events 

Endurance participation is growing, but the market is reorganizing around younger, mobile-first runners who register earlier and spend more. These shifts are changing revenue patterns, race distances, and event strategy across the industry.

1. The participant base is getting younger

• Millennials now dominate participation at roughly 43% of all racers, with Gen Z representing 21–25% depending on race type.
  
  
• Gen Z participation grew 33% year over year, the fastest of any generation.
  
  
• Older generations are gradually declining in participation, reflecting a generational handoff rather than shrinking demand.
  
  
• Contrary to stereotypes, marathons are trending younger, with Millennials and Gen Z forming the majority of marathon participants.
  
  

Implication: The long-term future of endurance events will be shaped by younger athletes entering earlier in their running lifecycle.

2. Registrations are happening earlier

• Participants registered 17 days earlier on average compared to 2024.
  
  
• Gen Z shifted registrations 25 days earlier, leading the trend.
  
  
• The first 60 days after registration opens generate 63% of total registration revenue, even though they account for only 35% of total registrations.
  
  

Implication: Early registration windows capture the highest-value participants and improve operational predictability for events.

3. Revenue per registration is rising

• Average registration revenue increased 36% year over year, rising from $78 to $106.
  
  
• Gen Z absorbed the largest price increase, jumping from $70 to $110 per registration.
  
  

Implication: The endurance market currently shows strong pricing power when value and experience remain strong.

4. Mobile is rapidly gaining importance

• Mobile registrations increased 92% year over year, while desktop registrations fell 17%.
  
  
• Mobile registrations generate 29% higher revenue per entry ($118 vs $91).
  
  
• Desktop still accounts for the largest share overall, but mobile is approaching parity among younger runners.
  
  

Implication: Mobile checkout performance increasingly impacts both conversion and revenue.

5. Race distance preferences are polarizing

• 5K participation share increased 15% and marathons increased 6%.
  
  
• 10K participation fell 18% and half marathon share dropped 12%.
  
  

Implication: Participants are gravitating toward either entry-level races or milestone endurance challenges, squeezing middle-distance events.

Overall conclusion

The endurance market is healthy but evolving. Growth is driven by younger runners who register earlier, transact on mobile, and accept higher prices. Events that optimize launch timing, mobile experience, and engagement with younger athletes will be best positioned for future growth.
