Lachlan David Morton (born 2 January 1992) is an Australian professional gravel and road racing cyclist, who currently rides for UCI WorldTeam EF Education–EasyPost.

[11][12][13] In 2015 "Thereabouts Reprise" was released about a 600-mile (970-kilometre) ride across the Colorado Rockies that Morton completed with his brother, and professional cyclists Taylor Phinney and Cameron Wurf.

[15][16] In 2019 Morton participated in the Unbound Gravel, Leadville 100, GBDuro and Three Peaks Cyclocross races as part of EF Pro Cycling's alternative calendar.

[21] He won Unbound Gravel in 2024 and rode the Tour Divide trail in 2023 in 12 days, 12 hours, and 21 minutes, becoming the fastest person ever to complete the storied route.

The feat garnered significant publicity, as Morton had made an attempt just days earlier which was disqualified by Hells 500, who stated that he had not reached the threshold to count as an Everesting.
