If you need to remove a race from your calendar, the steps depend on what type of race it is.
How to delete a supporting race (B or C race): If you want to remove a tune-up or supporting race, you can easily delete it directly from the app.
Go to your Home screen and open the My races card.
Tap on the specific race you want to remove.
Look for the trash can icon in the top right corner, next to the Edit Race button, and tap it.
Tap 'Yes' on the Delete Race prompt to confirm.
Why can't I delete my main goal race (A race)? Your main goal race (A race) is the foundation of your training plan. Because the app builds your entire running schedule around this specific date, it cannot simply be deleted with a button.
