Handcyclist Attila Domos of Greenfield laughs as he greets friends before his attempt to break German hand-cyclist Thomas Lange’s 24-hour world record of 403.8 miles on Saturday, Oct. 12, 2019, at the Uber test track in Hazelwood. He was forced to stop around 3 a.m. about 16 hours into the challenge without breaking the record. (Steph Chambers/Post-Gazette)
