The FOD Runner’s video on marathon training breaks down two key strength approaches. The takeaways are below so you can run the workout immediately. Watch the original for complete details.

Key points

• Two pillars of strength: (1) effort-based hill and threshold work on rolling trails, and (2) a short 15-minute kettlebell routine done twice a week.
• Trail fartlek: 12 × 2-minute intervals at roughly 10K race effort (push harder on climbs) with 1-minute easy float between each. About 24 minutes of hard work in a 35 to 36 minute session. For why this structure works, see Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them.
• Elevation focus: 2,500 to 3,000 ft of weekly elevation gain now, building to 3,500 to 4,000 ft.
• Kettlebell strength: start with an 8 kg kettlebell (working up to 10 kg), pick 3 to 4 exercises, do 3 sets of 10 to 15 reps each session, twice weekly after hard running days.
• Practical tips: gauge effort and pace on trails by feel (grade-adjusted pace helps). For dialing in effort, see Mastering the 10K: Proven Training Plans, Pace Strategies, and How a Smart App Can Elevate Your Performance. Schedule strength work on recovery days after hard efforts. Keep sessions brief and rotate exercises.

Workout example

Trail fartlek (12-2-1):

• Warm-up: 15 min easy run
• 12 × 2 min @ ~10K effort (push harder on hills)
  • 1 min easy float between each interval
• Total hard work: 24 min (≈35 to 36 min total)
• Cool-down: 15 min easy run

Kettlebell routine (15 min):

• Pick 3 to 4 moves (swings, goblet squats, single-leg deadlifts, press).
• 3 sets of 10 to 15 reps per move.
• Twice a week after a hard run. Skip on easy days.
