“Ride fast. Ride strong. Ride proud,” affirms soft-spoken transgender athlete Roxy Bombardier, the subject of filmmaker Jesse Huffman’s poignant new documentary, Claim the Lane: Becoming Roxy. Local audiences get the unique opportunity to preview the soul-stirring humanist portrait of identity at Main Street Landing’s Film House before it enters this year’s rigorous festival circuit. The made-in-Vermont flick follows Bombardier, an Iraq War veteran and cyclist training for the state’s most demanding gravel race, as she risks relationships with friends and family to live her truth and transition at age 51.
