Over its gritty 17-year existence Unbound Gravel has become one of the premier events in the sport, and will see 4,000 riders lining up in Emporia, Kansas, USA across five distances from 25 to 352 miles this weekend.
It is also the second event in the Lifetime Grand Prix series, which includes the Sea Otter Classic, the Leadville 100 and Big Sugar gravel, among others.
