No matter who you are, there will always be someone who can run faster than you.
Example: Steve Prefontaine who is arguably one of the most successful distance runners of all time, held the American record in 7 different track events from the 2,000 meters to the 10,000 meters. Even Prefontaine had lost some races in his lifetime yet he never gave up and always raced within himself and his ability.
Why compare yourself to your teammates or competitors who have different levels of ability. Comparing yourself to others creates a discouraging atmosphere you put yourself in whether it is in running or even magazines with photo-shopping . Instead of running as a healthy lifestyle or psychological outlook, you put yourself in an unhealthy mindset and compare your performance by how some else ran instead of your ability and personal records. Running should be fun and putting this pressure on yourself can cause you to lose sight of it. Instead you are running as a chore or punishment.
“Success isn’t how far you got, but the distance you traveled from where you started” –Steve Prefontaine. Run within yourself and always run because you enjoy it and never by force.
