That Dam TT is a time trial race in Baltimore County. The race is a challenging time trial around the Prettyboy Reservoir watershed. All proceeds from the race are donated to the National Multiple Sclerosis Society - Maryland Chapter.
For 2022 most races will be held on our normal 2 lap 50K (30.8 mile) course. All juniors and Senior 65+ races will be on a single loop. The technical route features 1,573 feet of elevation gain and has a maximum grade of 10.2% although the climbs average closer to 6%. There are many winding descents.
The first racer will start at 9:00am. Riders will be sent off by category. Exact start times are dependent on the number of registrants, and will be announced by 8pm on Friday, July 9th. Official results will be provided digitally once available from officials. Podium ceremony is planned at this time.
If you would like to warm up, please bring a trainer. There will be no warming up on Rayville Road or on the race course.
Roads will be open to traffic during the race.
