This Red Rock Dirt Spring is a 4-Lap Circuit Race on Mixed-surface, and pays out 150 Points towards the next Wristband and $10K to the winner (not counting bonuses).
Restrictions for this race are Class-A cars or below, with AWD drive types.
A few observations first... You will notice that the points you won from the rest of the previous Wristband races (following unlocking the Pink Wristband) are counting for the current one, which means fewer races before a band, though that is not an excuse not to run them!
Your rival for this series is Marko Baran, a Ukrainian gangster with more money than sense, and a willingness to both spend it on cars and tell you about it.
I am not sure what is more offensive -- having a rival smack-talk you about your skill (or supposed lack thereof) or having one tell you that they will outspend you to victory. Either way there it is.
The racing at this point and onward will be getting a lot less casual, and the AI seem to be a bit more aggressive, though that is not to say you find the same measure of aggression in them that you do in the real-world players in the online mode.
Speaking of the online modes, if you get to a point where you need a change of pace, remember that there are a handful of online racing Achievements in this game as well as the story-mode ones, so switching over to that can be a lot of fun and something else to do. Just saying.
If you do opt to try out the Online Racing you would do well to review the section of the guide (located at the top of the Reference area) that covers its three modes.
