Brawny, brainy, and with bleeding-hearts of gold, Blood Runners are the ultimate Life-Saving Crusaders.

The Service by Emergency Rider Volunteers (SERV) is a group of on-call volunteer motorcyclists who transport blood products during the night in emergency situations to hospitals outside of London, England. The public knows riders of SERV as (quite suitably) Blood Runners. Could you even think of a cooler super hero if you tried?
