5×10K

5x10K refers to a specific type of relay race event where a team of five runners each complete a 10-kilometer (10K) leg of the race. The total distance covered by the team is therefore 50 kilometers. This format is commonly organized for road races, trail runs, and sometimes even on tracks for shorter distance relays. The objective is for the team to achieve the fastest cumulative time across all five legs. Relay exchanges can occur at designated handover zones, where the next runner begins their leg after receiving a baton, a timing chip, or other designated item from the previous runner. 5x10K relays are popular for fostering team spirit and allowing runners of varying abilities to participate together. Teams often consist of runners from clubs, workplaces, or groups of friends. The strategic element involves choosing runners who can best contribute to the overall team performance, considering individual strengths in pacing and endurance. The event tests not only the individual running capabilities of each participant but also the team's coordination and support throughout the race.
