BestRacesCourse Builder · beta · free
Your course, in 3D
Drop the GPX and watch the course draw itself over real terrain — then fly it. Distance, climb, mile markers, aid stations — and your sponsors on the stations they paid for. Runs entirely in your browser; the file stays on your machine.

Course preview
Numbered dots are mile markers; a station with a sponsor attached wears an orange ring. Course lines are simplified for the web — runners should follow the official route, not this one.
Publish & embed it — free
One line of HTML on your race site · unlimited views · no watermark ransom
Publishing puts the course at a permanent link and hands you an embed snippet that works on RunSignup pages, WordPress, Squarespace — anywhere an iframe goes. Free, with your waypoints, sponsor cards, and the flyover included: a sponsored station shows "Presented by …" with a promo code and link when runners tap it — digital inventory your sponsors can actually click, not a logo in a race bag. We verify publishers by a sign-in link to your email; that's the whole signup.
