Long 80%:15%:5% here the physical aspect is more of a really strong engine that can keep going!
Middle 50%:40%:10%, in my opinion, the most technical one since hear you can't make any mistakes cause the race is to short to make up a mistake! It all comes down to try to make the perfect race.
Relay not last legs! 80%:10%:10% with strong physical skills you can use the other runners around you even if you are not the best technical person.
Relay last legs. 70%:10%:20%, of course, physical performance is important but here when you know we are running to decide positions it is often runners how are good tactical that often get high positions!
P.S. Skills mean an orienteering technique; Tactics means the interaction with other runners and pacing during the race.
