TARC Blue Hills Skyline Trail Run Milton, MA   Jul 11, 2026

The TARC Blue Hills Skyline Trail Run is a gnarly, old school 12K race with approximately 2,300 feet of climbing. The course is on the Blue Hills Reservation North & South Skyline Trail. The terrain is rocky and steep and will demand your attention, balance, and agility. In addition to epic staircase climbs and tumbling rock downhills, runners can expect a classic New England path through the woods with East Coast technicality and scenic views of the Boston skyline (if you dare to look up from the rocks under your feet)!

​Course markings and on-course support are minimal – this race is not for the directionally-challenged or faint of heart! Markings will follow skyline blazes with a few signs at critical points.

Hydration pack or handheld bottle are required. There will be water stops with light refreshments at the finish.

This race is no frills, no bibs, and a TON of fun. You’ll be pushed to your max and will love every second (we hope!).
