This 10-week marathon training plan is tailored for runners who have previously completed a marathon in under 3:20 and are aiming to break the 3:10 barrier. The plan focuses on building aerobic endurance and improving the capacity to sustain a higher power output over the marathon distance.

Key components of the plan include progressive long runs that develop aerobic efficiency, structured tempo runs to raise the lactate threshold, and steady-state runs to enhance the body's ability to maintain a strong pace over time. Recovery days and adaptive training weeks are integrated to promote consistent progress and mitigate the risk of overtraining, ensuring runners stay healthy and motivated.
