teams and run for an hour. This allows us not only to study the individual relationship between age and performance but also … performance goes down with age, although the speed-age gradient is rather flat. Group performance goes down with age as well, but … interestingly a counterbalancing force emerges, namely team dynamics that are driven by performance of runners who enter and leave. …
