I have a time in chemical reaction that is both the fastest all medals, and fastest overall run. I never did the run intending to upload it to here, but it was intended to be an all medal time, but is also faster than the "Fastest" run record. I see no reason as to why I can't do this, but I'd like to check before uploading.

I wish that was a thing as well. If you wanna see the current best times tho, check out Arkhamknight699 on youtube. He set the world record for every single race shortly after the games release despite having no competition. The times are insane, and have all remained as record until recently, where the youtuber KillerTrainZ -_- has beaten four of them.

If you are curious about the race/combat hybrid races, I have all three records on my channel domthebomb016, tho these times haven't been as optimized as the standard races.
