Marathon Training Over 40

Training over 40 isn't about doing dramatically less than you used to, or than a younger runner does. The main practical shift is that recovery generally needs more deliberate attention than it did in your twenties or thirties, and training plans that ignore this tend to catch up with runners eventually, usually through nagging injuries rather than one dramatic setback.

What genuinely tends to change

Recovery between hard sessions often takes a bit longer, which means back-to-back hard days are riskier than they might have been earlier in life. Many runners also find they need a slightly longer general warm-up before a session feels loose, and that niggles, when they show up, take a little more patience to resolve fully. None of this means slower overall progress is inevitable, it usually just means the training needs to be built a bit more deliberately around recovery.

What doesn't automatically change

Plenty of runners in their 40s, 50s and beyond run personal bests, complete their first marathon, or significantly improve their fitness. Age alone doesn't set a ceiling on what's achievable, and it's easy to over-attribute a slow patch in training to age when the actual cause is inconsistent training, insufficient recovery, or simply a normal rough training stretch that happens at any age.

Practical adjustments worth making

• Prioritise 1-2 full rest days a week over squeezing in extra running volume, especially during a marathon build.
• Build in a proper warm-up, 8-10 minutes of easy movement before a hard session, rather than starting cold.
• Add strength training twice a week if it isn't already part of your routine. Maintaining muscle and joint resilience becomes more relevant to injury prevention over time.
• Space hard workouts further apart, allowing a genuine easy day or two between quality sessions rather than back-to-back intensity.
• Pay closer attention to sleep and general recovery habits, since their effect on how training feels tends to become more noticeable.

Setting goals that reflect reality, not doom

If you're returning to running after a long gap, or starting for the first time at 40 or beyond, the same principles in how to start running from zero still apply, gradual build-up matters more than age itself. If marathon training is the eventual goal, understanding what differs between a half marathon and a full marathon is worth reading before committing to a first marathon block, since the fuelling and recovery demands are real regardless of age.

Listening to your body without overreacting to it

There's a balance between reasonable caution and unnecessary self-limitation. A day that feels sluggish doesn't automatically mean something is wrong, and persistent, worsening pain shouldn't be brushed off as 'just age' either. If something feels genuinely off and doesn't resolve with rest, it's worth getting checked by a doctor or physiotherapist rather than guessing, the same advice that applies to runners of any age.
