Pacing strategies during the swim, cycle and run disciplines of sprint, Olympic and half-Ironman triathlons An Australian group has studied the pacing behavior of triathlets via Sprint, Olympic Distance and Halber Ironman.8 male triathlets were analyzed during swimming, cycling and running.
The speed remained constant at all routes. When cycling, the pacing was not uniform.When running, the triathlets in the sprint were able to grow towards the end (negative pacing), while they were always slower over Olympic distance and halfway, see [Positive Pacing), see https://pubmed.ncbi.nlm.nih.gov/25557388/
