回答: Maybe try Olympic Distancew Triathlon is more realistic 由 HunHunSheng 于 2006-7-17, 08:30:53:
Sprint is most popular one in USA. 750 m swimming,
20 KM biking, and 5 KM running.
Judging by triathlon, can we draw conclusion that
so far as endurance is concerned, one unit
of running is equivalent to 4 unit of biking?
