About this race
core4 gravel is a ride-and-run event in Iowa City, Iowa, with the promise of “no surface untouched.” It takes place over two days in August and is built around mixed-surface riding and running rather than a single road, trail, or gravel-only format.
The event site separates the course, run, training, FAQ, and safety information, so it reads like a practical participant weekend, not just a race listing. core4 also has its own kits, posted results, and photo booth and podium galleries, with community, opportunity, recreation, and engagement stated as its core values.
