After a 2-year pandemic induced hiatus, a much-anticipated competition returns! The 37th NIH Institute Challenge Relay will be held on Wednesday, Sept. 21 in front of Bldg. 1, beginning at 11:30 a.m. 

The relay consists of teams of five runners, each of whom runs a half-mile loop around Bldg. 1. All institutes, centers, divisions and contractors are invited to enter as many teams as they wish. Each team must have at least 2 women runners and at least 2 men runners. 

In years past, clever team names and humorous costumes have added to the fun of the competition.

To register for this R&W event, visit: The fee is $20 per team. 

Each group leader is asked to provide the name and contact information for one volunteer; 26 volunteers for each of two heats are needed. 

Food vendors and event exhibitors will be on site as well. To volunteer or for more information, email David Browne at
