The XRUN Grande Finale marks the end of the XRUN series, taking place in the Beskid Wyspowy mountains of southern Poland. It is typically held in autumn, when the cooler air often aids runners in achieving fast times on the course.
The start line features participants who have competed against each other earlier in the series, giving the finale the feel of a season's final gathering rather than a standalone race. Following the event, the series presents awards to the top athletes from the entire XRUN cycle. The finish line brings together the broader community of runners who have participated in the series throughout the mountains.
