Trail Run 9/3

Trail Run 9/3 focuses on trail ultras and shorter trail races centered on dirt, rocks, climbing, and extended time outdoors. The most notable event is the Twisted Branch Trail Run, a 100K in the Finger Lakes Region of upstate New York. It begins at 5 a.m., sending runners into the woods before dawn. The Texmas Trail Run offers a Texas edition at Buescher State Park in Smithville, with distances ranging from 1 mile to 104K, including a four-person relay for the longest distance. Twisted Branch is the more challenging mountain-style run, covering approximately 64.5 miles with six major climbs, three exceeding 1,000 feet, and around 11,000 feet of elevation gain. Texmas utilizes repeated loops on narrow paths and singletrack, featuring rocky sections and smaller inclines, with about 450 feet of climbing and descent per loop. The 104K participants complete nine loops, while those in the 57K, 21-mile, 14-mile, and 7-mile races run fewer laps from the same start-finish point. Texmas limits participation to 500 runners and features Texas-themed aid stations stocked with drinks, sweets, salty snacks, PB&Js, bean burrito rolls, fruit, bandages, and Vaseline.

Fifteenth Charles River One Mile Swim

The Charles River One Mile Swim is a one-mile open-water race in Boston. It starts and finishes in the water at The River Dock near the Arthur Fiedler statue by the Hatch Shell on the Esplanade. The race takes place in early June, begins in the morning, uses chip timing, and is open to swimmers age 18 and older. It is part of the United States Masters Swimming New England Open Water Swim Series. Swimmers can earn a series prize by completing five of the seven listed swims. The course is a loop on the Charles River between the Harvard and Longfellow bridges, with the Esplanade alongside much of the swim. The Charles River Swimming Club organizes the event. This club was formed to organize competitive swims and support public swimming in the river. Its first one-mile race in the Charles basin was the first sanctioned public swim there in more than 50 years. The event acknowledges the river cleanup work that began in the mid-1990s. The race often fills up, and volunteers help make the small, tightly managed swim function.

About cycling & running in Boston

Boston Training Notes

Running: Locals run the Charles River Esplanade first, because the bridges let you pick your distance and the bathrooms and fountains make long-run logistics easy. You can run an 8-mile loop between Harvard Bridge and Longfellow Bridge, and the Storrow Drive section gives you 3 miles when you want clean Z2. The Emerald Necklace runs over seven miles through continuous green spaces all the way to the Arnold Arboretum, with Jamaica Pond, Back Bay Fens, and Franklin Park in the mix. Boston Run Club meets at DICK'S House of Sport on Saturdays at 8:00 am for 5 to 16+ miles, and Heartbreak Hill Running Company brings Signature Speed on Tuesdays and Thursdays. The Boston Marathon is the anchor event, with Run for Recovery 5K and DAV 5K Boston filling the calendar.

Cycling: Locals ride the Charles River Bike Path for a 23-mile loop, then use the Minuteman Bikeway through Arlington, Lexington, and Bedford to reach Walden Pond. Charles River Wheelers keeps the group-ride scene busy with hundreds of rides annually, and New England Randonneurs puts the Boston Brevet Series on the long-day calendar. Greater Boston NEMBA covers the MTB side when singletrack calls. The typical loop runs 7 km with 220 m of elevation. The west side brings the hilly countryside, while Concord, Carlisle, Dover, Needham, Blue Hills, and Bellevue Hill handle the climbing work.

Season: Spring and Fall are the best months, and Boston feels built for base miles when the air is steady and the paths stay busy. Summer hits 5 °C, so locals run early, keep intervals honest, and save longer rides for cooler windows. Winter changes the rhythm. Winter drops to 1 °C, storms can bring heavy snow, the immediate coast often gets more rain than snow, and the smart move is layers, good gloves, shorter Z2, and trail or indoor options when the footing gets messy.
