Challenge Races are a category of Chao Races in Sonic Adventure 2 which are unlocked after finishing all of the Beginner Races. The Challenge Races are among the hardest races in the game, and generally follow the same course that the Diamond Races follow, requiring a Chao to excel in all stats, especially running and stamina, to emerge victorious. The Challenge Races include 12 races, with very rare and strange opponents (including some which are not even Chao.)
Unlike the prizes for the Beginner and Jewel Races, the prizes for these races are unlocked for the whole of the Chao Garden and allow several Chao to play with them at a time. Winning the fourth race will provide a ball for Chao to kick and chase, winning the eighth race will provide a Jack-in-the-Box, like those which appear in races, and winning the 12th, and final, race will provide the garden with a television for Chao to watch together.
Races
Each Race takes place on courses of similar design than those from the Jewel race, specifically Diamond, Onyx and Peridot. These can be seen below.
Rivals
Challenge! The strong Gold and Silver Rivals! - Diamond Course
This race is against Gold and Silver Jewel Chao, all of which are neutral and adults, along the same course as the Diamond races.
He returns. - Diamond Course
While this race has seven opponents, the only opponent of consequence is Chacron, a two-tone grey Chao making his return from Sonic Adventure. The other racers are baby Chao with a variety of animal parts and features from Gradual Evolution.
I'm trying! - Peridot Course
This race is against Omochao opponents, robotically running forward.
Small animal challenge. - Peridot Course
The opponents in this race are notably not Chao, but Small Animals which you would generally find in levels and feed to Chao. Blue, black, and orange group animals will not appear in this race.
Horrible! Cockroach Chao group. - Onyx Course
This race is against "Cockroach" Chao, which are all Onyx Jewel Chao, with dragon antennae. These Chao are all evolved, into Neutral, Dark, or Hero evolutions.
Oh, My Egg! - Peridot Course
This race is against full-egg Chao. These Chao are walking eggs, only having visible feat. These Chao are missing emote-balls.
Be afraid! Skeleton group. - Diamond Course
This race is against baby Chao, each having a skull hat. This race takes place on the same course as the Diamond races, however it is also on the dark version of the course, also used in Hero Races, complete with dark lighting, dead trees and tombstones along the path. Unlike the Hero Races, however, the music is unchanged from normal Chao races.
Be afraid! Pumpkin group. - Diamond Course
This race is against baby Chao, each having a pumpkin hat. This race takes place on the same course as the Diamond races, and is like the previous Skeleton Group race, being on the dark version of the course.
Be afraid! Ghost group. - Diamond Course
This race is against baby Chao, each of which has no legs (provided by bats) and a flame ball (provided by half-fish). Some Chao may have pumpkin or skull hats as well. This race takes place on the same course as the Diamond races, and is on the dark version of the course, completing the trio of spooky challenge races.
He strikes back. - Diamond Course
This race is a redo of the challenge race 2, He Returns. However, Chacron will be a superior racer from before.
Kid's troops Chao ranger. - Diamond Course
This is a race against a group of brightly colored Neutral Chao, comprising their own Super Sentai or Power Rangers-like team. In the DC release, these Chao are Jewel Chao, while in the GameCube and later releases, these Chao are Shiny Chao.
Here comes the ultimate rival! - Diamond Course
This is the final challenge race, 1-on-1 against a Light Chao. The course is the same as the Diamond races. Although it's difficult to tell, this is actually the hero version of the course, also used in Dark Races.
Prizes
The following garden toys can be won from the Challenge race:
| Race to beat | Toy | Image | Description |
|---|---|---|---|
| Challenge Race 4 | Ball | 
|
The chao may run after the ball and knock it around the Chao garden. The player can also pick up and throw the ball. |
| Challenge Race 8 | Jack-in-a-box | 
|
The chao may use the Jack-in-a-box in the same way it is used in the races; it can contain either nothing, or a surprise. |
| Challenge Race 12 | Small TV | 
|
The chao may watch TV, with several different 'programs' that can be watched. |
Rivals & Other Chao
"Rival" Chao are those that appear in the same race consistently with the same stats and appearance. Every race has anywhere from 0 to 7 rivals. Non-rival race opponents have random stats taken from a certain range appropriate for each race. Being a rival Chao does not necessarily mean that that Chao has the highest stats of the opponents (although they certainly can be the most challenging opponent.) The rivals of each Challenge Race, and their stats, are shown:
