Poland’s mega festival: multi-distance mountain chaos with a headline 240K and nonstop race-week energy.
The Dolnoslaski Festiwal Biegow Gorskich 100 Mile Trail is a 170km ultramarathon starting in Dlugopole-Zdroj and finishing in Ladek-Zdroj through the Sudetes of Lower Silesia, Poland. Introduced in 2025 as a new DFBG distance, the race is in only its second edition in 2026. The course gains 5,193m D+ and descends 5,109m D- (30.6 m/km) -- a near-balanced profile (38.6% uphill / 23.3% flat / 38.1% downhill) -- with a 38-hour cut-off and a 05:00 Friday start. The race carries 6 ITRA points and is a UTMB Index 100M event, capped at 150 runners. At 8.26% distance-weighted average uphill gradient and -8.25% average downhill gradient (both LOWER-MID tier, near-perfectly symmetric), the 100 Mile Trail is defined by sustained moderate-gradient effort across 170km and one full night rather than by extreme individual pitches. The course opens with a 5km climb from km 0.03 (6.95% avg) and closes with a 5.28km technical descent into Ladek-Zdroj (Descent 3, km 166.20). At km 122, the course crosses the Srebrna Gora hanging bridge -- a distinctive landmark where crew support is restricted. The inaugural 2025 edition course records stand at 19:16:51 (men: Jakub Gorzelańczyk, who also holds the DFBG 130km CR) and 23:26:00 (women: Justyna Folenga). Wroclaw Airport (WRO) is approximately 105 minutes from the festival base; transport to the Dlugopole-Zdroj start requires planning. Entry costs 480-540 PLN (~EUR 0.65/km); 150-person cap with registration open at b4sportonline.pl. The finish in Ladek-Zdroj is the festival base itself, making post-race logistics more straightforward than the 130km sibling.

Q: What is the DFBG 100 Mile Trail 170km? A: The DFBG 100 Mile Trail (Polish: Sto Mil Trail) is a 170km ultramarathon through the Sudetes of Lower Silesia, Poland, starting in Dlugopole-Zdroj and finishing in Ladek-Zdroj.

The course gains 5,193m D+ with a 38-hour cut-off and a 05:00 Friday July 17 start, capped at 150 runners. It carries 6 ITRA points and is a UTMB Index 100M event -- the strongest qualifier credential of any DFBG distance.

Course Profile -- Cold Start Climb at km 0, Hanging Bridge at km 122, Descent Into the Finish▼
Q: How hard is the DFBG 100 Mile Trail 170km? A: Demanding at the duration and volume level rather than through extreme gradient. The course carries 5,193m D+ over 170km (30.6 m/km) with an 8.26% distance-weighted average uphill gradient and -8.25% average downhill gradient (both LOWER-MID tier) -- a near-perfectly symmetric profile. The race opens with a 5km climb from km 0.03 and closes with a 5.28km technical descent into Ladek-Zdroj after 166km. Runners complete one full overnight period (05:00 Friday to cut-off ~19:00 Saturday). No DNF rate data is available for the 2025 inaugural edition. The 38-hour cut-off, overnight element, and balanced 170km gradient demand are the primary challenges.
