Looking for a fast, flat, PR-capable course to chase your Boston dreams? The I’m Bound for Boston Marathon & Half Marathon delivers exactly that—on a uniquely “super-fast” 1-mile loop at Northfield High School, northwest of Denver. Launched in 2025 by Five Star NTP, this intentionally boutique race caps at ~150 half-marathoners to focus on performance and pacing.
Starting sharply at 6:30 AM MDT, runners enjoy chip-timed loops, mile-split clocks, and live pacing support—all designed to help shave precious minutes off your Docker. The marathon course is USATF-certified and Boston-qualifier, with the half sharing the exact same flat layout. Music and energizing entertainment at each mile help break the monotony of repetition.
Registration is tiered: early ($71.56), regular ($82.56), late ($93), and race day ($103) . Spot limits ensure a controlled field and high-quality experience. Volunteers can run free by recruiting crews—ideal for pacing teams or pace-group support .
While it’s not a scenic downtown course like Colfax, it’s ultra-efficient—with no course crowding and all focus on fast laps. One reddit runner from a similar Denver loop event in June said it was “overcast in the 50s… perfect weather for a run”.
For Boston hopefuls or anyone chasing a milestone tempo, this targeted race is built to deliver results: flat, fast, focused—with no frills and no angle out.
