Plan Description

Built for competitive runners targeting the 2026 CNO Financial Indianapolis Monumental Marathon who have a strong mileage base and are ready to add serious quality to their build.

• Plan start date: July 4, 2026
• Race day: November 7, 2026
• 18-week progressive training structure timed specifically for Monumental Marathon race day
• Heart rate-based training to keep easy days easy and hard days hard
• Weekly mileage starting at 32 miles and building to 55–58 miles at peak
• Long runs up to 21 miles, including 14 miles at marathon pace
• 2–3 tune-up races built into the schedule to sharpen fitness before November

This plan is for you if:

• You've consistently handled higher mileage in previous training cycles
• You're ready to move beyond base building and add real quality workouts to your Monumental prep
• You want a structured, data-driven approach to hit a competitive goal time in Indianapolis
