Craddock raced in the 2018 Tour de France with race number '13'. He crashed during the first stage, causing a hairline fracture in his scapula, but continued racing. After that crash, he took to social media announcing he was donating $100 for every stage he finished to the Greater Houston Cycling Association in the rebuild of the Alkek Velodrome, where Craddock got his start in cycling and which was damaged by Hurricane Harvey. A GoFundMe page was also set up for people to make direct donations to the Alkekvelodrome in Houston, Texas. Craddock finished the race as the "lanterne rouge", becoming the first rider in Tour history to hold last place after every stage and earning nearly US$200,000 for the cause.
