Uppsala is the fourth-largest city in Sweden, located approximately 70 km north of Stockholm, with a population of roughly 177,000 residents. The demographic profile of Uppsala is approximately 75% Swedish-born, with a significant international student and professional population; the largest foreign-born groups originate from Iraq, Iran, and Syria. The median annual household income in the region is roughly 345,000 SEK. Geographically, the Hågadalen-Nåsten area is a fault-block landscape characterized by flat-topped rocky plateaus and clay-filled valleys. The climate in mid-April in east-central Sweden is typically cool and crisp, with average lows of 1°C (34°F) and highs of 11°C (52°F). Trail runners should prepare for potential mud in the low-lying valley sections following the spring thaw.
The race center is located at the OK Linné clubhouse on Tallbacksvägen, where toilets and limited parking are available. Organizers strongly encourage participants to arrive by bicycle or public transport due to the limited parking capacity. Registration includes a post-race burger and drink for all participants, and energy stations along the course feature sports drinks from Umara. Awards are presented to the top three male and female finishers in the 45 km, 15 km, and 7.5 km categories. While online registration closes on the Tuesday before the race, late registration is possible on-site via Swish, though post-race catering is only guaranteed for pre-registered runners. Participants compete at their own risk and are encouraged to review the GPX files provided by Ultra Uppsala prior to race day.
