Marathon training and fitness

Even though my first marathon didn’t go as fast as planned, the training really improved my fitness, evidenced by a solo 5k PR of 16:39 (from 16:54) two months after the marathon.

At first marathon training was really hard for me. My coach and I settled on training for 2:40-41, based off of mile and 5k recent PRs since we didn’t really have any recent longer PRs to go off of, but I had adjusted well to the threshold training and increased mileage. It seemed very ambitious to me, but my coach really believed I could handle 6:08/mile marathon paced (MP) workouts.

The first workout (8 miles @ MP) was solid, but the second one was warm and humid and felt so long! Granted since my half marathon PR at the time was 6:05 mile pace running 10 miles at 6:08 felt overwhelming. I began to fall only a few seconds off pace and felt very overheated so stopped at 8 miles, then ended up running a few miles easy and did one mile at threshold. Overall a solid session. For a beginner maybe starting at 6 miles, then 8 miles would be more appropriate. Another option –especially in hot or windy weather or with sudden training fatigue – would be to break up the session into say 2 x 5 mile at marathon with one mile easy recovery.

Nonetheless the next 2 marathon LR sessions (12 continuous miles, 15-16 continuous miles) I was able to complete without issue. Interspersed between marathon sessions I still ran threshold miles in LRs (2-4 miles worth) and completed 2 depletion runs (22 miles). For these depletion runs I cut down on carbs the day prior, and only drank water and black coffee in the am before, consuming nothing during.

Weekday workouts consisted of threshold 1- 2- 3- mile repeats (6-8 miles total) with equal minute active recovery and continuous runs alternating marathon and threshold miles (5-6 miles total). It was a hard adjustment cutting out interval training, as I was so accustomed to getting these sessions in every week basically ever since I started running! However, focusing on a new area – marathon pace – as well as building my mileage up to 80-85 miles/week, running further than I ever had (22 milers), as well as continuing to run faster threshold workouts really helped me feel stronger and like I had so much more endurance.




You never know what FL coastal weather will be 😄
