Pacing Strategies of Ultra-Cyclists at the ‘Race Across America’. So far, there are few investigations like the speed resp.Performance for very long endurance charges. We have examined the change in the speed of the ‘Race Across America’ from 2010 to 2014, taking into account the influences of height differences as well as temperature and wind. On the basis of a formula we have also tried to estimate the watt performance.It turned out that the speed decreased continuously during the race with the men faster than the women. The calculated watts also decreased in the course of the race and was also deeper for women compared to men.For women, the watts was lower for all finishers compared to men, the threeast per year and the finishers in the age group 60-69 years, but not for the finishers in the age groups 18-49 and 50-59 years.Temperature and altitude differences had an impact on the decrease in speed and wattage for both sexes who investigated performance and age groups.
Only in the age group 50-59 years, temperature and altitude had no influence on the driving speed. The work can be found under https://pubmed.ncbi.nlm.nih.gov/26215121/
