From the Organizer
The Upton 10.5K and Half Marathon Trail Race, set in Upton State Forest in Upton, MA, has two races: a 21K (a half marathon with two laps) and a 10.5 K. Runners will navigate single tracks and forest roads. There is about 720 ft of elevation gain per lap. Those who register early will receive TVFR Upton Trail Buff. There are aid stations at the Dean Pond turn and the Park Rd/Loop Rd intersection, spaced roughly every 3 miles.
Post-race festivities will feature fire pits, hot soup, and hot chocolate. Awards include "Custom Made" trophies for the top male and female overall, and age group awards recognize the top three in various categories.

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
