Add in these three key sessions per week to PR at your next 5K, 10K or half-marathon.

Want to translate your hard-earned triathlon fitness into some running personal bests? Try this simple six-week plan that focuses on two or three key workouts per week to get you race fit.

This plan assumes you have been running 3–5 hours per week, are injury-free and have recovered fully from your “A” race. You can still do the other two disciplines, but keep your “quality” work around running. Depending on your fitness level and typical volume per week, you can work in other easy runs outside of this schedule.
