Winners 10:39:48 (men) and 14:49:03 (women).

Series page describing Winterman as a one-way park course with a downstream icy-water swim past a large buoy in darkness, 3,000+ m (9,840+ ft) of bike climbing and a trail run ending on Ještěd. Promotional, organizer-side.
- Wikipedia - Extreme triathlonaggregator · Mixed
Lists Winterman as an active full-distance XTS race with about 4,700 m (15,420 ft) of ascent, first held 2015, and a distinctive roughly 9 km (5.6 mi) downstream swim claim (disagrees with organizer's 3.8 km (2.4 mi) / 2.4 mi).
