This is also my plea to add the 100 Challenges section. The time I submitted is for that category. It expires in 13 days, I am in the Rider Speedruner discord and can try to provide another downloadable version of the video, will try uploading it to YT.

Mod: verified 50 Challenges run with a time of 39m44s. 100 Challenges category just created and ready for submission.
