Thank you Aras and others who asked - “How to react when someone overtakes you?”.
This is the same as handling adversity when you are in a race, or in life. The main parts to this are:
1) How to prep for an event with defending in mind (as a small part of the prep).
2) How to drive when someone is catching and attempting to pressure you.
3) What to do when you are overtaken
I hope this helps
