How to Join a Race

To join a race, you must be mounted on an eligible ModN Equine horse while the race join window is open.
For the full guide, see Racing With Your Horse.
Step 1: Watch for a Race Announcement
Races are scheduled and announced in-game.
The announcement tells players that a race is coming up and gives time to prepare.
Step 2: Prepare Your Horse
Before joining, check:
you are mounted on the horse you want to race
you have permission to race that horse
your horse has enough energy to enter
your horse meets the race's Speed XP and Jump XP requirements
you meet any rank requirement
you are holding the required Riding Crop or Pro Riding Crop in your main hand
Step 3: Join the Race
When the join window is open, use:
/joinrace
Joining closes 10 seconds before the race starts.
Step 4: Stay Ready
A countdown begins 5 seconds before the race starts.
Keep the required crop in your main hand until the race ends.
Leaving a Race
To leave a race, dismount from your horse.
You will be returned to the location where you were when you used 
/joinrace.
