Dolnośląski Festiwal Biegów Górskich

Q: What is the DFBG K-B-L 110km? | A: The K-B-L 110km (Kudowa-Braszowice-Ladek) is a standalone trail race that follows the return leg of the 240km Bieg 7 Szczytow (Seven Summits Run) -- Poland's longest trail race. The course runs point-to-point from Kudowa Zdroj Park Zdrojowy to Ladek-Zdroj through the Sudetes mountains of Lower Silesia: 110km and 3,667m D+ (~33.3 m/km). Start: 17:00 on Friday July 17, 2026. Time limit: 26 hours (finish by ~19:00 Saturday). 6 nutrition points. 400-person cap. Part of the Dolnoslaski Festiwal Biegow Gorskich (DFBG), the mega-festival drawing ~5,500 participants, 14th edition in 2026. NOT sold out. 390 PLN standard entry. NOT FAR: Wroclaw Airport (WRO) 105 minutes. Note: the course runs the 130km Super Trail in reverse -- the 130km's hardest descents become the K-B-L's defining climbs, and vice versa.

Q: How hard is the DFBG K-B-L 110km? | A: The K-B-L 110km is a genuine mountain 100 at an accessible difficulty level within the European trail running spectrum. At 8.47% DW average uphill -- rank 311 of ~390 GPX-tracked courses in the DTR database, with 310 courses steeper and only ~79 gentler -- the profile sits in the bottom ~20% for gradient steepness: Pre-Alpine, runnable, sustained. The Sudetes peaks here remain below 1,000m; terrain is beech forest trails, dirt roads, and highland paths. The challenge is distance and cumulative fatigue, not technical terrain or extreme gradients. The steepest section is Descent 3 (km 82.92, -10.00% avg, GPS-confirmed) -- 2.55km technical descent in the final quarter. The Friday 17:00 start means a full overnight run, adding psychological and navigational challenge. July Sudetes weather brings afternoon thunderstorm risk and temperature swings from warm valleys to cooler ridges.

Q: What is the relationship between the K-B-L 110km and the 130km Super Trail? | A: They are mirror courses -- the same terrain run in opposite directions. The 130km Super Trail runs Ladek-Zdroj to Kudowa-Zdroj (northeast to southwest). The K-B-L 110km runs Kudowa-Zdroj to Ladek-Zdroj (southwest to northeast). The 240km Bieg 7 Szczytow consists of both legs run sequentially: 130km runners who complete the first leg at Kudowa-Zdroj become the starting field for the K-B-L return. Standalone 110km runners join at the same start point. This means the K-B-L's biggest climbs are the 130km's biggest descents, and vice versa. The K-B-L 110km has a slightly gentler average uphill (8.47%, rank 311/~390) than the 130km (9.04%) but slightly steeper descents (-8.96% vs -7.88%), reflecting the reversed direction. Both are Pre-Alpine Sudetes courses.

Q: What is the DFBG festival and what else happens during race week? | A: The Dolnoslaski Festiwal Biegow Gorskich (DFBG) is Poland's largest mountain trail running festival, held annually in July in Ladek-Zdroj, Lower Silesia. The 14th edition runs July 16-19, 2026. The festival draws approximately 5,500 participants across distances ranging from 5km to 240km, hosted across four days. Beyond the races, DFBG includes a trail running expo, podcasts, meet-the-elite sessions, and the festival atmosphere of Ladek-Zdroj -- a historic thermal spa town. Distances in 2026 include the 240km Bieg 7 Szczytow (flagship), 130km Super Trail, 110km K-B-L, 55km and shorter distances. For international runners, the festival format makes a visit worthwhile even if only entering one distance -- the race village in Ladek-Zdroj is a genuine event hub.
