2026 Windermere Marathon - Jun 14 Race Completed

Q: What is the Windermere Marathon route?

The Windermere Marathon is a point-to-point road course that starts at Waterhead, Ambleside and finishes at Brockhole on Windermere. From the start it heads north, crosses the River Brathay past High Wray, then loops down the quieter western and southern shores of England's largest lake - through Hawkshead, Near and Far Sawrey, Newby Bridge and Bowness - with fell and lake views throughout. Over half of the 26.2 miles is run on partially traffic-free roads or roads with a dedicated running lane.

Q: Is the Windermere Marathon flat? How hard is it?

It is not flat - it is a hilly, honest road marathon. The course rolls constantly around the Lakeland shoreline for roughly 600m of total ascent, with no single big climb but very little flat. Most runners finish well outside their flat-course time. Plan your effort with our pace calculator and study the rolling profile with our elevation profile tool before race day.

Q: How much climbing does the Windermere Marathon have?

The point-to-point route packs in approximately 600m of total elevation gain (some GPS tracks read closer to 620-630m). It is spread across constant rolling rises rather than one long ascent, which is exactly what makes the Lakeland roads tougher than the elevation number suggests. Expect the hills and the June humidity together to add a meaningful chunk to a flat-marathon time.

Q: What surface is the Windermere Marathon and what shoes should I wear?

It is a road marathon, run on partially traffic-free Lakeland roads and lanes rather than off-road trail, so normal road shoes are the right choice. A little extra cushioning helps on the rolling descents over 26.2 hilly miles. There is no need for trail shoes - this is tarmac and quiet country road, not fell or gravel path.

Q: How do I enter the Windermere Marathon 2026, and is it sold out?

Entry is handled online by The Great Run Company, which relaunched the race in 2025 (the event was previously run by the Brathay Trust through 2024). The standard entry fee is 75 GBP. The 2026 marathon is sold out, so if you miss out, watch the official site for 2027 entries or look for charity places. It is a single-distance, marathon-only event.

Q: What time does the Windermere Marathon start and what is the cut-off?

The marathon starts at 8:30am from Waterhead Car Park, Ambleside (LA22 0ES) on Sunday 14 June 2026. The published time limit is in the region of 6 hours 30 minutes; confirm the exact cut-off and any intermediate course-closure points in the official event guide, which is released about a month before race day.

Q: Is the Windermere Marathon a Boston Qualifier?

Treat it as no. The organizers market it as a scenic point-to-point road race, not as an accurately measured, road-certified course, and it has not been confirmed as a UK Athletics-certified Boston-qualifying race. A hilly net point-to-point profile is also a poor choice for a qualifying attempt. Come for the Lakeland scenery, not a PB. If a qualifying time is your goal, check the standards with our Good For Age tool and pick a fast, certified road race instead.

Race Information

Race	2026 Windermere Marathon - Jun 14
City	Ambleside
Date	2026-06-14 at 08:30
Time Limit	6 hours 30 min
Cutoff pace	9:15/km
Timezone	Europe/London
Official Site	The Great Run Company

Race Day Weather

Average Temperature	13.2°C / 56°F
Humidity	84%
Wind	22 km/h
Rain Chance	55%
Typical Conditions	A mild but changeable June morning in the Lake District. Expect around 12-15C (54-59F) at the 8:30 start, climbing into the high teens by midday, with high humidity and a genuine chance of rain or low cloud rolling off the Cumbrian fells. The lake valley can be still and muggy or breezy and wet within the same hour.

What to Prepare: Dress for mid-teens Celsius and carry a light waterproof - Lakeland weather turns fast, even in summer. This is a road course, so road shoes are fine, but expect to run slower than a flat marathon: the rolling +600m of climbing and lake-valley humidity both take a toll. Pace by effort on the hills, not by your flat-course splits.

Wind Impact on Race Day

Wind at 22 km/h can affect your marathon pace by 5-15 seconds per kilometer. Headwinds slow you down exponentially — a 20 km/h wind costs more than twice a 10 km/h wind.

How do I get to the Windermere Marathon, and where do I stay?

The start is at Waterhead, Ambleside, in the central Lake District. The nearest railway station is Windermere (a short bus or taxi from Ambleside), reached by changing at Oxenholme on the West Coast Main Line. Many runners drive, but parking is limited and the finish is at Brockhole, so check the official travel and shuttle information. Book accommodation early in Ambleside, Windermere or Bowness - this is a busy summer tourist area.
