BibBoard.ai was born from a simple frustration: missing race registrations. If you've ever discovered that Boston Marathon lottery closed yesterday, or that Big Sur sold out in three hours while you were at work, or that UTMB's lottery acceptance rate is 40% and you didn't even know to enter — you understand the problem.
We built BibBoard to be the tool we wished existed. A single platform where endurance athletes can discover races across every discipline — marathon, trail, ultra, triathlon, HYROX, Spartan, CrossFit, cycling — and never miss a registration window again.
BibBoard tracks registration windows, sell-out risk, difficulty ratings, and race intelligence for 5,000+ endurance events worldwide. Our data pipeline runs 24/7, monitoring registration status changes so we can alert you the moment something opens — or warn you before it sells out.
Race rankings on BibBoard are never for sale. Our sell-out leaderboard, difficulty scores, and race recommendations are based entirely on real data — historical sell-out timelines, course profiles, and community knowledge. No race organizer can pay to rank higher. No affiliate commission influences what we recommend. If a 5K with no affiliate program is a better choice for you than a sponsored marathon, we'll tell you that.
This isn't a marketing position — it's a foundational principle. The moment you can't trust a recommendation platform, it becomes useless. We'd rather earn less money honestly than more money dishonestly.
Transparency matters. BibBoard earns revenue through:
Affiliate commissions — When you click a registration link and sign up for a race, we may earn a small commission from the registration platform (like RunSignUp). This costs you nothing extra.
Hotel referrals — When you book accommodation near a race venue through our hotel partners, we earn a commission. Again, no extra cost to you.
Gear recommendations — Our gear page features products with Amazon Associates links. We earn 4-10% when you buy through those links.
Alerts PRO — Our premium subscription ($4.99/month or $39.99/year) gives you unlimited watchlist slots, SMS alerts, and priority notifications.
None of these revenue streams influence our race rankings or recommendations. Ever.
