Past National Time Trial Champions
The USA Cycling Professional Time Trial National Championship was held for the first time in 2006. The USPRO ITT is now part of a dual championship for professionals with the Road Race, now hosted by Greenville, S.C. on Labor Day weekend. This "race against the clock" championship is open to any U.S. citizen on a UCI-registered trade team. In the past, professional riders were included in the USCF Elite Men's National Time Trial Championship event.
But since the professional aspect of the sport continues to grow in America, it became possible to feature a time trial for professional riders only similar to the structure of the road race.| YEAR | CYCLIST | TEAM |
