When you cross the finish line of a marathon, you’ve accomplished something very, very special.

Especially designed for the intermediate to advanced level age group triathletes, the goal of this 12-week Marathon Training Plan for Triathletes is to set you up for YOUR MARATHON SUCCESS while maintaining a reasonable level of swim and bike sport-specific fitness.

coach and athlete krista schultzHand-crafted by USA Triathlon-certified coach and elite triathlete Krista Schultz, MEd, CSCS this plan encapsulates her exercise physiology expertise with more than a decade of experience as as an endurance athlete and coaching hundreds of other athletes to success.

A typical week consists of 4 run, 2 swim, 2 bike and 2 strength workouts. During the plan, you will build up to 3 hours running. Your weekly schedule includes optional time allocation for strength exercises and a designated off day (Monday). We recommend using a heart rate monitor in conjunction with perceived effort, but a heart rate monitor is not required.

Please note: This plan starts any time so pick your start day 12 weeks before your target race day (week one is race week). This plan version assumes your target marathon race is on a Saturday Sunday.

Purchase of this plan includes our comprehensive ENDURANCEWORKS Training Plan Guide, which explains how to use your training plan, and, as an added bonus, Build and Maintain: Strength Training for Triathletes.

• Swim: 1500 meters or yards continuously
