Does one naturally run their easy runs faster in the morning or do I have a tendency to overtrain in morning runs?

which country?

If you start running and it's a lot cooler out than usual, then I would definitely expect you to run a bit faster than normal. Temperature makes a gigantic difference.

Just keep an eye on your heart rate and make sure you don't go too crazy (if it's an easy run)

I live in southeast Brazil, and even though it's winter down here, it's definitely not cold late afternoon, early evening.

But, the mornings can be quite pleasant.

That's what I want to know, do you think that a 10-15s per km (more like 10 I guess) difference is reasonable based only in the temparature variation?

Because it feels so good and easier to run in the mornings, that I really don't know if I'm running really easy or if I'm pushing myself ever so slightly (what would surely add up if done on every easy run) just because maybe it's easier to push myself in the cold.

I am the same, anything but easy running is hard at the end of a working day whereas even tougher long runs on empty in the AM feel a (relative) breeze.

I have a hard time getting started in the mornings right after waking up, but the weather is much better suited in a warm/humid place for running early than in the evening, when it's still hot and humid and there are often t-storms storms in summer. The difference between cool and hot weather can be more like 1-2 minutes a mile, depending.

I don't have the habit of running in the morning as I have a hard time waking up early, instead I usually run in the middle to late afternoon or early evening. And in the very few runs that I did in the morning I noticed that I tend to run significantly faster with pretty much the same effort.

So I was thinking is that something normal or is simply easier to push yourself when it's cold.

For note, I live in a tropical country, by this time of the year it's pretty normal to have a 13 °C min and a 27 °C max (55.4 ° to 80.6 °F)?

Really I'm the opposite. I get up and run first thing in the morning everyday and am a morning person but I still run faster in the afternoon when my body has had a chance to warm up.

The heat of a very hot day does not impact my easy runs, only hard workouts or races.

I don't live in a tropical climate but Southern California is pretty mild, low 40's F is about as cold as it gets here. Over the summer it does get to the 90s.

Yes it is much easier to run faster at the same perceived effort when it is cool out compared to hot. What the means for specific times is a bit individualized but it is easier for everyone when it is less hot.

Absolutely. Temperature could account for an even more dramatic change in pace than the one you just described.

Remember how easy running starts to feel once summer is over and cool fall weather arrives?

You beat me to it. In 6 years of running doubles, it never occued to me to compare morning and afternoon paces.

Normal to be faster in cool weather all else being equal. Personally I’m slower in the morning as I age and wake up with stiff joints.

I highly agree with the first reply. There’s some case study articles show that runners get more fitness gains and able to get more quality miles and run faster in cooler temperatures (55 degrees F- 70) it makes a worlds different than suffering to run in hot humidity above 85.
