you run hard-core throughout the year, then upgrade your running gear
on a continual basis. For example, shoes may look fine from the exterior,
but the sole may actually be worn out inside. Bring the issue into a
store and compare it with a new pair to get a feel for what kind of
condition the running shoe really is in.
Replacing other types of running gear is more a matter of taste. While
wearing worn-out shoes can impact your bones and health, it's up to
you to decide when to replace clothing. It's a matter of style and budget.
For example, manufacturers are always introducing new styles of running
gear. That doesn't necessarily mean you have to get a new jacket each
year. Still, for some people with the extra bucks having the latest
gear is part of the fun of the sport.
