As noted above, unlike most multi-day bicycle races such as the Tour de France, RAAM has no stages, i.e., there is no specified distance to travel each day. Also, with the abandonment of the Enduro concept, there are no designated rest periods for food and sleep. Actually, sleep is optional.

The clock runs continuously from start to finish as in a time trial, and the final overall finish time includes rest periods. Thus, the winner is the rider who can best combine fast riding with short and infrequent stops. The winner usually finishes in eight to nine days, after riding approximately 22 hours per day through the varied terrain of the United States.

The addition of the 8-person team division has enabled finish times of slightly over five days.[9] Each racer or team has a support crew that follows in vehicles to provide food, water, mechanical repairs and medical aid. During the night, a vehicle with flashing lights is required to follow each rider to ensure safety.

Having to ride continuously for days with little to no sleep puts this event in the ultramarathon category. The continuous physical output places considerable strain on the competitors as well as their support crews. As many as 50% of solo participants drop out due to exhaustion or for medical reasons. In addition, the race takes place on open roads, forcing participants to deal with sometimes dangerous traffic conditions. This represents another major difference between RAAM and more traditional bicycle road races.
