This was followed by a 65-km UM (elevation ± 1093 m) consisting of three laps (each 21.7 km). Methods: 15 male UM runners (mean age 45 ± 5.7 years) completed a standard exercise test (mean VO 2max 48.8 ± 3.4 ml⋅kg -1⋅min -1) for determination of the individual testing speed (60% VO 2max: mean speed 9.4 ± 0.7 km/h). We examined RE before, during, and after a 65-km UM. Controversy remains if RE increases, decreases, or remains stable in UM running. Purpose: Running economy (RE), expressed as oxygen cost (O 2 cost) and energy cost of running (Cr) is important in ultramarathon (UM) running as it can help predict race performance. 2Department of Exercise and Health, Institute of Sports Medicine, Paderborn University, Paderborn, Germany.1Ultra Sports Science Foundation, Pierre-Bénite, France.But the reward for enduring these shortcomings is an unparalleled opportunity to experience untold human strength.Volker Scheer 1,2*, Solveig Vieluf 2, Leoni Cramer 2, Rasmus Jakobsmeyer 2 and Hans-Christian Heitkamp 2
Regrettably also, the coverage of the diversity of cultures and geography they ran past was necessarily cursory (note pun opportunity here). At a few points when the team's mood was low, the film sank into an uncomfortable, bitchy reality TV format. Given the impossible terrain-with sandstorms, heat, and access to virtually no local technology-the cinematography is outstanding, capturing the unimaginable beauty of the desert and handsomeness of the lonely, unfamiliar places the runners encountered. Words to live by! Anyone who sees this film is likely to consider expanding his or her personal goals. At the end one of the runners comments that we are all limited by the goals we set for ourselves. The documentary's biggest strength is its realistic account of ways that team members dealt with the inevitable struggles among them and with the doubts in each one's minds about the constant challenges, mental and physical. Running 4,500 miles is something most of us will never do, so how lucky we are to have a film that shows three men and a small support crew doing exactly this.
