I got a few questions why do you need 2 ppl to do it and what would happen if i complete the race? will it reset the world record? or will it go off of the last world record I had?
You need 2 people only to start the race, then the world record should automatically be 7 minutes, then you keep on beating the world record, everytime you do, you get RP and after race it should reset back to the 7 minute world record and it might depend on your console platform
You should be able to do it as many times as you want, and make sure the game says your beating or setting a new world record, not a personal best, two different things they are, and after it should reset back to a 7 minute world record and could depend on what console platform you are on
