What happens to your body when you start running?
When you start running, your muscles’ oxygen needs immediately spike, but the time it takes for the rest of your body to respond is dictated by your ‘oxygen kinetics’, or response time.
Why do some people run faster than others?
You’re not running fast enough to accumulate high levels of lactate and other metabolites; and, unlike in a marathon, you’re not running far enough to empty fuel stores. So why does it eventually – and inevitably – get so hard?
Why is it harder to run at a faster pace?
Over the course of a sustained run at half-marathon pace or faster, the amount of energy (and thus oxygen) needed to maintain that pace gradually inches upward. Over the course of 10-20 minutes, your oxygen consumption can drift upward by as much as 25 per cent, making it progressively harder for you to hold your pace.
Why do I have less energy at the end of a run?
To meet the energy shortfall, your muscles tap into their anaerobic (oxygen-free) fuel stores. That produces metabolic by-products that make your muscles feel fatigued – and it also leaves you with less energy for the final anaerobic sprint at the end of the run.

Why do I run slow all the time?
Common Reasons Why You are Running Slow. To summarize, there are usually one or more of these issues present if your performances have plateaued: Not getting enough quality sleep. Experiencing too much stress. Not eating enough calories. Low iron levels. Weather considerations. Eating insufficient amounts of carbohydrates. Not running long runs.
Why is it so hard to run 5 miles?
After a few weeks of skipped or missed long runs, your fitness declines and faster speeds seem more difficult. You’re simply not building the endurance base you need to support your other workouts. A “normal” run of 5 miles may now be a lot closer to your long run – and it will feel that way! So do yourself a favor and prioritize the long run.
