Kernave-Vilnius Trail 42km: Baltic Forest Trail Marathon from Silėnai to Vilnius -- Top 12% Flattest in the DTR Database, GPS Navigation, and a Capital City Finish

The Kernave-Vilnius Trail 42km (branded the 42KM Suunto MARATONAS) is a point-to-point trail marathon from Silėnai village to Vilnius, the Lithuanian capital. It runs the second half of the same course used by the 82km ultra distance, covering ~80% dense Lithuanian forest and the Neris River valley. The course delivers ~950m D+ over 42km (~22.6 m/km; D+/km rank 328/~390 -- near-bottom of the DTR database), with PctFlat rank 342/~390 (top ~12% flattest). Start: 10:00; 8-hour time limit; 2 aid stations. GPS navigation required. Finish in Vilnius city; Vilnius Airport (VNO) is at the finish city. Part of the Kernave-Vilnius Trail multi-distance event (82km, 42km, 21km, 10km). 2026 race (June 13) has passed; next expected June 2027.

Yes -- one of the most accessible trail marathons in the DTR database for road runners. D+/km rank 328/~390 (less dense than ~84% of catalogued courses), AvgUphill rank 295/~390 (gentler than ~76% of the database), and PctFlat rank 342/~390 (top ~12% flattest). The top single ascent ranks 351/~390 -- near the smallest in the database. The average descent is among the top ~22% gentlest (rank 88 inverted). The primary demands are: sustained 42km effort on forest trail (soft ground, roots, uneven surface), GPS navigation (must follow GPX track -- no course markings), and two aid stations across the distance with an 8-hour time limit. Expect trail pacing to be 10-20% slower than road marathon pace despite the flat profile. A road marathoner with 4-5hr fitness and a GPS watch for navigation is well-equipped for this event.

GPS navigation is required for all 82km, 42km, and 21km distances. The course is NOT physically marked -- runners must have the GPX file downloaded to a sports watch or a mobile phone with a navigation app. The final GPX file is typically released ~2 weeks before race day; a preliminary GPX is available earlier via kernavetrail.lt/courses/maratonas. Runners should practice loading and following a GPX track before race day. The 10km distance format may differ -- VERIFY at kernavetrail.lt. Navigation in dense Lithuanian forest with the Neris River valley adds an adventure element above the gradient difficulty: junctions may be unmarked, and forest tracks can look similar. Download the GPX well in advance and check it on a training run before the event.

Entry fee for the 42km: VERIFY at kernavetrail.lt or dbsportas.lt -- the 82km sibling distance is approximately 65 EUR; the 42km is likely lower (estimated 35-55 EUR). Registration is via the Lithuanian sports portal dbsportas.lt (dbsportas.lt/lt/varz/2026003). 2026 race (June 13) registration is now closed; check kernavetrail.lt for 2027 opening. Runners receive: GPS tracker (check current year rules), race bib, and finisher medal for sub-cutoff. Part of the same event as the 82km ultra -- the 82km ultra runners start earlier on the same day; there is a shared race atmosphere at finish in Vilnius.

The race FINISHES in Vilnius, making logistics unusually straightforward for international runners. Vilnius Airport (VNO) is at the finish city -- fly in, race to the finish line, fly home. Direct flights to VNO from many European cities (Ryanair, Wizz, LOT, and others). Start (Silėnai village): approximately 40-50km from Vilnius city -- race organisation typically provides transport from Vilnius to the start, or runners arrange private transport. Accommodation: Vilnius city centre has strong accommodation options at all price points (5-star hotels, boutique guesthouses, Airbnb, hostels). Vilnius Old Town (UNESCO World Heritage Site) is a 10-15 min walk or short taxi from most finish areas. Race pack collection: verify location and times at kernavetrail.lt -- expected day-before or morning of race in Vilnius.
