As a nurse and runner, I get it — some days it feels like there aren’t enough hours in the day to do anything, let alone build your running endurance. Between 12-hour shifts, life responsibilities, and that post-work fatigue, training can easily slide to the bottom of the list.
But here’s the good news: you don’t need endless miles or hours of training to improve your endurance. You just need to be intentional with the time you have. Here’s how I make progress even when my schedule is packed.
1. Prioritize Quality Over Quantity
When time is limited, every mile counts. Focus on runs that have purpose — think tempo runs, long runs, or intervals — instead of just logging “junk miles.” Even 30–40 minutes of focused running can build endurance when done consistently.
2. Use Your Short Runs Wisely
Can’t fit in a long run? Break it up. Two shorter runs in a day (like one before and one after your shift) can mimic the benefits of a longer session and train your legs to handle fatigue.
3. Add Strength Training
Building endurance isn’t just about running. Squats, lunges, calf raises, and core work improve your running economy and make every mile feel easier. I often do 10–15 minutes after my run or before work — no gym needed.
4. Embrace Cross-Training
If your schedule doesn’t allow for more runs, cardio like cycling, rowing, or even brisk walking on your break can add to your aerobic base without extra pounding on your joints.
5. Make Recovery a Priority
When your time is short, recovery can easily get overlooked — but it’s where the real gains happen. Sleep when you can, stretch after runs, and use simple tools like a foam roller or massage ball to keep your muscles happy.
Bottom line: You don’t need hours and hours of running to build endurance — you just need a smart plan and consistency. Small, focused efforts add up fast, even in the busiest seasons of life.
