leaf blower and kart repair were in older 2.0 versions but they got removed
the karts are slower there, but they have more powerups like turbo karts or leaf blower
arctic super bounce and zig-zagging is specific to two episodes, the former i named it due to the odd suspension when landing, and the other is when you gain height from constantly steering left/right in the air tracks
all characters - unlock every character, it's only relevant for 1.0 as in 2.0 it's the same as any%
jenga% - finish jenga as fast as you can, timer starts when loading is finished
season% - unlock all of the seasonal karts (recommended to use 1.12.0 to 1.13.9 as they have all of them), best used with date and time exploit
seasonmax% - same as the above, but you need to max upgrade them
any% no powerups - same as any% but no powerups (king sling, turbo kart, leaf blower, kart repair)
telepods% (unlikely) - scan every telepod in the game, you can use qr codes to make it easier (it works for both 1.0 and 2.0, but best on the first since the ones in 2.0 only unlock downgraded karts)
individual episodes% - for 1.0, this will include all of the 5 episodes, but for 2.0 it will include the 11 unlockable characters :bomb - chuck
max% - max out and unlock every kart, unlock every character and 100% every episode
100%- get all episodes to show the challenge rounds counter, so you need to get all modes of each track to have a challenge
i know 1.8.7 is the best one but the mod i found doesn't have the rest of the episodes, but the others i found were 60fps and i don't know if that's allowed since it only makes the game smoother and not impact on other things
i think the servers shut down but the latest one removed all of the modes except for the weekly race set
also add if powerups are used or not, as well as the ability
you should add which version it is run at, for example my sub zero time is from 1.4.3
it only works in versions before 1.10.0, as i checked
in certain 1.0 versions, if you complete a race and the results screen appears, you can click the topbar and click change racers, which will allow you to skip the score tally, it might be useful for a run
there should be speedruns of each cup or just all of them
