I’m Jeremy Criddle. I write the ADHD Runner book series, and long-distance running — including ultra-distance — is a real, ongoing part of my own life, not a topic I picked because it seemed profitable.
This site is different from the rest of the network I run: it’s a reference database, not a review or affiliate site. The goal is a genuinely useful record of the top 100-mile ultramarathon races in the US — organizer contacts, course details, aid stations, past finisher times, registration methods — kept accurate rather than padded with opinion content.
How This Data Is Maintained
Race details change year to year — courses get rerouted, registration methods shift between lottery and first-come, aid station counts move. This is an ongoing reference, not a one-time publish, and it’s treated that way.
