The Story

Timberman is one of the oldest 70.3 races in the United States, and it occupies a special place in American triathlon. Held in late August in New Hampshire's Lakes Region, it falls at the exact moment when the New England summer begins its turn toward autumn — the first red and gold leaves appearing in the canopy above the bike course, the lake water still warm from summer but the morning air carrying the first hints of fall.

The lake swim in Ellacoya State Park is freshwater, 20°C, and surrounded by forest that reflects in the still morning water. Lake Winnipesaukee is New Hampshire's crown jewel — a vast body of water dotted with islands and ringed by the foothills of the White Mountains. The swim course traces the shoreline, and on a calm August morning the water is glass-flat, the mist rising off the surface in wisps that burn away as the sun climbs. You swim through liquid silk, the water dark but clean, with the treeline reflected so perfectly that the boundary between water and forest dissolves.

The bike heads into the New Hampshire hills — rolling terrain through covered bridges, past white-clapboard villages with church steeples, and up climbs that are short, sharp, and relentless. Seven hundred metres of climbing accumulates in the way New England hills always do: just when you think you've finished one, another appears around the corner. The roads are quintessential New England: narrow, winding through forest and farmland, lined with stone walls that settlers built two centuries ago. In late August, the sugar maples are just beginning to turn — touches of orange and red among the dominant green, a preview of the spectacular foliage that will transform these hills in October.

The run follows the lakefront, flat and shaded by the trees that are beginning to show colour. The path is smooth, the lake provides constant visual company, and the late-August light — warm but with the first hint of autumn's golden angle — makes even the hard kilometres feel like something worth remembering. The New England triathlon community is fiercely loyal to Timberman. Many athletes return annually, and the race has a reunion quality that newer events can't replicate. You see the same faces at registration, the same families at the same spectator points, the same finish-line celebrations that are equal parts athletic achievement and community homecoming.

Timberman is New England in a 70.3: the lake, the hills, the leaves, the community. It launched a thousand first 70.3 finishes for athletes who drove up from Boston, New York, and the Connecticut suburbs, and it's the race that veterans keep coming back to long after they've checked off more exotic destinations. There's no volcanic landscape here, no Swiss Alps, no Mediterranean glamour. There's a New Hampshire lake at dawn, forest roads turning gold, and the particular satisfaction of racing through a landscape that's been living quietly and beautifully for centuries.

The post-race lobster roll at a lakeside shack is not technically part of the course. It should be.

"Timberman is the first hint of autumn. The leaves are just starting to turn, the lake is still summer-warm, and the racing feels like saying goodbye to the season in the best way possible."

"The New Hampshire hills don't look hard. They are hard. They're just short enough that you never get a rhythm, and there's always one more."

New York triathlete — Post-race report

"I've raced Timberman seven times. Every year I swear I'll do something different. Every year I come back to the lake."

Boston veteran — Pre-race registration

"Swimming in Winnipesaukee with the mist rising and the forest reflecting — it's the most peaceful race start I've experienced anywhere in the world."

What It Feels Like

Timberman is the New England 70.3 — a race defined by its lake, its hills, its community, and its season. The swim is peaceful and beautiful. The bike is a rolling New England challenge that rewards punchy fitness and rewards patience. The run is flat, scenic, and lakeside. What makes Timberman special isn't any single feature — it's the accumulated character of a place and a community that have been doing this for twenty years. The late-August timing catches the transition from summer to autumn, giving the race a seasonal poignancy that newer events in more exotic locations can't replicate. This is a race people come back to — not because it's the hardest or the fastest, but because it feels like home.

🏊 The Swim

Lake Winnipesaukee: freshwater, 20°C, and still. The lake is vast — the largest in New Hampshire — and the swim course traces a shoreline section that's protected from wind by the surrounding hills. On a calm morning, the water is glass-flat with mist rising from the surface. The temperature is comfortable enough that the cold isn't the story. What's memorable is the atmosphere: the forest reflecting in dark, clean water, the silence broken only by splashing and birdsong, and the particular beauty of a New England lake at the cusp of autumn. Sighting is straightforward — buoys and shoreline are always visible. This is a swim that feels special, not because it's challenging, but because it's beautiful.

🚴 The Bike

New England rolling hills: 700m of climbing through covered bridges, white-clapboard villages, stone walls, and forest roads. The climbs are short (1-3 minutes) but frequent and steep — New Hampshire terrain rewards punchy power, not sustained climbing. The roads are narrow, winding, and quintessentially New England — every corner reveals a new view of farmland, forest, or distant mountain. In late August, the first touches of fall colour appear in the canopy: orange maples among green birches, a preview of the spectacular transformation that's weeks away. The road surfaces are generally good but variable — watch for patches and root damage on the shaded forest sections. There's a particular joy to riding these roads: they feel lived-in, historic, and unself-consciously beautiful.

🏃 The Run

The lakefront run is flat, shaded, and paced by the views. Lake Winnipesaukee provides constant visual company — dark water, forested islands, distant mountains — and the path is smooth and well-maintained. The late-August temperature (20-25°C) is ideal for running. The trees that line the course provide welcome shade, and the spectator support is concentrated at the start/finish area and at key turnaround points where the New England triathlon community gathers. The two-lap format means you know the terrain the second time around, and the lakeside setting provides enough beauty to keep your mind occupied when your legs would rather quit.

Legendary Moments

2004

Timberman Launches

One of the first 70.3 races in New England debuts at Lake Winnipesaukee. The late-August timing and lakeside setting immediately establish it as the region's defining half-distance race.

2012

The Biggest Field in the Northeast

Timberman draws over 2,500 athletes, making it the largest 70.3 in the northeastern United States. The race's growth reflects New England's triathlon boom and Timberman's status as the region's must-do event.

2019

The Glass-Calm Morning

A windless August dawn produces mirror-flat lake conditions. Athletes describe the swim as 'swimming through a painting.' The mist, the reflections, and the silence create a race-morning atmosphere that becomes the standard by which other Timberman mornings are judged.

2023

The Early Foliage Edition

An unusually early turn of the sugar maples produces significant fall colour on the bike course. Athletes ride through corridors of orange and red that shouldn't appear until October. New England's unpredictable seasons deliver an unexpected gift.
