Spin with the group that is faster than you, or run with a friend who is in better shape. It may sound like an annoying idea, but it actually works as a boost for your motivation.
Trial bikes
This was the outcome of a study in which subjects had to cycle. When they were told that another group, who was also cycling, was faster, the cyclists lasted longer. Even when they thought that the time of the first person who stopped cycling became the end time of the team, the subjects cycled longer than when they cycled alone.
Challenge
When someone is faster or better than you, chances are you will last longer. So don't stay too long with the beginner sports class and feel free to go for a run with a friend who is slightly more advanced than you.
Do you like playing sports with people who have a higher level than you?
