1.) Sudden changes in training causes injury
One of the main causes of running injuries is rapid alterations in training frequency, duration and intensity.
Why? Your muscles haven’t developed the endurance strength required, leading to increased fatigue, poor foot placement, decreased pelvic stability and eventually….injury.
Let’s look at a scenario. You usually run three times a week, for 10kms, along a flat trail. In 4 months you have enrolled in a 21km mountain run. How do you change your training without injury?
How to train for a half marathon
a. Frequency: Start training by adding a shorter run, an additional day per week. Don’t try running six days, straight away! Fatigue and DOMS (delayed onset muscle soreness) will be far too much for your body and you'll end up injured.
b. Duration: Running for 1.5 hours, three days a week is where you’re at - so increase by increments of ten minutes per fortnight. You’ll be at 21kms in no time, but don’t force it straight away.
Overuse injuries are most common in runners with sudden increases in training duration. Shin splints? No thanks!
Hill Running
c. Intensity: This is the clincher. You may wake up feeling energised and stronger than ever one morning, but don’t be tempted to sprint up the biggest hill you can find. Running uphill puts huge stresses on the achilles tendon and hip flexors. When they’re not conditioned for hill running, the excessive loading and propulsion forces lead to tendonopathies (tendon conditions) and inflammation.
