WTA legend Martina Navratilova was among several to bash Austin Killips after the transgender cyclist finished in first place at the Belgian Waffle Ride in North Carolina.
Killips won in 8 hours, 28 minutes and 7 seconds, beating out Paige Onweller by about four minutes and Flavia Oliveira by seven minutes.
However, Navratilova and several others were not happy with the result.
"What a joke," the former tennis star tweeted.
Killips gained the national spotlight last month after becoming the first transgender woman to win a UCI event. Since then, the uproar has caused USA Cycling to ask its members about transgender participation in the sport.
