2026 Spring Endurance Training

We built our training plans to provide a balance of miles, intensity and recovery.

We offer three 11-week training plans for half marathon runners, and an 8-week training plan for 10K runners. Whether this is your first, fifth or fifteenth event we have a plan for you. Our flexible plans are based upon your race!

Our RRCA (Road Runners Club of America) certified coaches will help guide you to meet and exceed your goals.

Training plans are online using StrideOn Running, where you can view your plan on any Internet connected device. You can easily upload and update training runs and compare them to planned runs to track your progress.

We have group runs three days per week

• Wednesday night, 6 PM meeting in the parking lot behind the BMO Harris Bank at 155 W Wilson St., Batavia, IL 60510.
• Saturday and Sunday morning, 7:00 AM, starting at the Fabyan Windmill at the Fabyan East Forest Preserve, Shelter #3. We will send a confirmation email earlier in those weeks in the event there is a change in place and time.
  • Saturday group run includes multiple pace groups.

Our flexible training plans can be adjusted for any half marathon or 10K. You may join our group runs at any time; however, the "official" start dates for training are 11 weeks before your scheduled half-marathon race date, or 8 weeks before your scheduled 10K race date.

HALF MARATHON TRAINING PLANS: We offer three different plans for the half marathon. Select the plan that fits your experience during registration.

• Blue Plan - Level 1: You will generally run 4 days per week. For the half marathon, you will start with a 14-mile week including a long run of 5 miles, working up to a 25-mile week and a long run of 11 miles. In general, select the Blue Plan if you are new to distance running or have experience but need a more manageable load. However, if you have a good or significant mileage base and can manage a greater load, consider an Orange or Purple Plan.
• Orange Plan - Level 2: For the half marathon, you will run 4-5 days per week, starting with a 23-mile week including a long run of 7 miles, working up to a 30-mile week and a long run of 12 miles. Consider this plan if you have a good mileage base and have some experience as a distance runner.
• Purple Plan - Level 3: This plan calls for running 5 days a week. For the half marathon, you will start with a 29-mile week including a long run of 9 miles, working up to a 38-mile week and a long run of 14 miles. Consider this plan if you have a significant mileage base and are an experienced distance runner or have endurance racing experience.

10K TRAINING PLANS: We offer two different plans for the 10K. Select the plan that fits your experience during registration.

• Blue Plan - Level 1: You will run 8 - 15 miles per week with a long run of at least 6 miles. In general, select the Blue Plan if you are new to distance running. However, if you have other racing experience and the mileage base, consider the Orange Plan.
• Orange Plan - Level 2: You will run 12 - 18 miles per week with a long run of at least 7 miles.

Experience is not necessary, but in order to enhance your opportunity for success, we strongly encourage you to have an adequate training base in place before entering the program. We recommend the following:
