In my opinion, a 5K race is the perfect blend of speed and endurance. Many runners fall into the trap of feeling like the only way to improve their time is to just run. But there's more to it. An efficient 5K-race plan consists of the following four elements:
Running is a highly repetitive activity. A weak, inefficient gait leads to a slower race time and a painful racing experience. A strong and stable body is a key to finishing fast and feeling good. (See Strength Training for Endurance Athletes.)
When preparing for endurance events, runners lean toward overtraining and logging too many miles. Instead, get out to a track or the local hills and work on your speed over shorter distances while increasing your leg strength. (Check out endurance athlete Chris Legh's Hill Repeats.)
This is an overlooked, yet extremely important aspect of race training. Mixing up your preparation by adding some swimming or spinning will help you avoid literally running your body into the ground. Your body will respond faster to the speed training and you won't overdo it on the roads. (Try these options: Suffering from Burnout? Athletic Benefits of Cross Training.)
In any training plan, rest is crucial. (Read Your Guide to Optimal Recovery.) Exercise breaks your body down, and recovery gives you time to build it back up and come back stronger.
