I think there's marathron run.
The idea for the modern marathon was inspired by the legend of an ancient Greek messenger who raced from the site of Marathon to Athens, a distance of about 40 kilometers, or nearly 25 miles, with the news of an important Greek victory over an invading army of Persians in 490 B.C
If it's pre medival time, maybe there's a guy who literaly run 42km just to diliver message. Either order or demon lord.
And if you wanna add the taste, Mamono will hunt you all the way. And who reach finale without losing liquid is the winner.
And If you wanna add the taste 2, you guys pair with mamono and do a steel ball run.

Another is flying racing, I also wanna see which harpy species is the fastest.
The harpy also has an item drop contest. Who can drop an item in the circle with most accuercy wins.
