Gauja Trail by UTMB – Gauja Trail 20 K
Cesis
Race guide
Updated 18 July 2026
The Gauja Trail 20K by UTMB is a 21 km loop from the historic town of Cesis in Latvia's Gauja National Park. With only 406 m of total climbing and a high point of just 108 m, it is one of the flattest, fastest entries in the UTMB series — a race built for speed and for runners taking a first step into the trail world rather than for mountain specialists. Starting and finishing at around 104 m, the course rolls through the forested river country of the Gauja valley with a single checkpoint at Ozolkalns near halfway. The generous Saturday 20:00 cut-off makes it accessible to a wide range of runners, from those chasing a quick time to first-timers who want to complete the distance comfortably.
The course and terrain
The route is a loop that starts at 104 m, passes a checkpoint at Ozolkalns at 11.3 km (105 m) and returns to the finish at 20.7 km (104 m). The near-identical elevations at start, midpoint and finish tell the story: this is flat, low-lying terrain in the Gauja valley, with the whole course sitting close to 100 m and a high point of only 108 m. With just 406 m of climbing spread across 21 km, there are no sustained ascents to break the rhythm. Expect rolling forest and river-valley trail rather than mountain paths, on a course where the challenge is holding a strong, steady pace rather than surviving big climbs. The single aid point at Ozolkalns near halfway means you should plan to carry what you need for a roughly 10 km stretch between support.
Where the race is shaped
Because the elevation barely moves — 104 m at the start, 105 m at Ozolkalns, 104 m at the finish — this is not a race decided by a single decisive climb. The 406 m of gain comes in small, repeated undulations rather than one defining ascent, so the race is shaped by consistency: the runner who keeps turning over a fast, even effort across the whole loop will come out ahead. The checkpoint at Ozolkalns (11.3 km) is the natural split. Reaching it feeling controlled, rather than having chased a fast early pace on the flat opening kilometres, sets up a strong second half back to Cesis. On terrain this runnable, small pace lapses cost more time than they would on a steep course, so the mental discipline of staying honest through the middle kilometres is what separates a good result from a fading one.
How to pace and fuel it
This is a course to run, not hike. With a 20:00 Saturday cut-off and only 21 km of flat trail, the time limit is comfortable for almost everyone, so pacing is about extracting a good time rather than beating the clock. Start controlled on the fast opening section, settle into a rhythm you can hold, and use the flat profile to run steadily all the way to the finish. Fuelling is simple on a race this short and this flat, but the single aid point at Ozolkalns means planning for roughly 10 km between support in each direction. Carry water and a gel or two so you are not reliant on a single stop, and top up at Ozolkalns before the return leg. In warm conditions the lack of altitude means little natural cooling, so prioritise steady hydration even though the distance is modest.
Conditions to expect
The Gauja 20K runs low and flat through Latvia's Gauja National Park, so the conditions are dictated by the forest and river valley rather than by altitude — the entire course sits near 100 m. That means no exposed high ground and no mountain weather, but also little natural cooling, so heat and humidity can be a factor on a warm day. Low-lying river-valley trail can hold moisture, so footing may be soft or slick in places after rain even though the profile is gentle. With a high point of just 108 m and a well-spaced single checkpoint, the practical demands are modest: dress for the day's temperature, carry enough water for the two roughly-10 km segments around Ozolkalns, and be ready for fast, runnable ground from start to finish.
