Central bearded dragon's are ~1lb reptiles and can do 25MPH which is faster than most people.
So, at least predator dinosaurs where likely faster than most people. We might do fine over long distances, but overall we are fairly slow.
As to being warm blooded, that's less meaningful for very large creatures. Body feathers are also a sign something is trying to conserve body heat which is a sign it's warm blooded.
Trained humans can maintain a speed of ~20kph for hours (as in plural). Peak speed for a few seconds (which is what would be required to escape these animals if reaction time is not the problem) is ~50 kph for humans (but only for 10 meters or so).
Apples to apples, humans are far superior to these speeds. The best animals for these measurements do crush these figures (by a factor of ~3), but I would expect that the best dinosaurs wouldn't.
Very large animals are effectively warm blooded by default due to volume to surface ratios cooling is a much larger problem than staying warm.
True, but being "very large" does not really help with either top speed or explosive power. The fastest animals are small (though not tiny, a decent-not-huge dog in size but much lighter) brittle little things. They chase, rapidly inflict a mortal wound, and run away, waiting until it is abandoned to eat. Fast animals, from cheetahs to rabbits are much lighter than their appearance would suggest. The animals with greatest endurance are larger, but humans are, perhaps surprisingly, pretty good at endurance. Clearly we, at one point, hunted like dogs do : not by outsprinting an animal in an intense fast chase, but by wearing it down for hours, slowly closing in for the kill. Most animals should not be able to escape humans using that strategy. Human hunters would make an animal sprint for it's life 10 times, letting it "escape" 9 times.
Trained humans can maintain a speed of ~20kph for hours
The very best humans can only manage ~20kph for 2.05 hours (WR: 42.2km in 2:02:57 giving 20.59kph). Beyond that, the 50km WR is down to 18.3kph; 100km WR is 16.1kph; etc.
Endurance runners are not generally strong. Upper body strength for example is counter productive.
Further, Olympic paces are maintained by people getting aided with sports drinks at regular intervals etc. It's very different from the conditions primitive people would have lived.
The drastic difference between 12mph and 25mph is where our problems would show up. Many predators can do 20+ mph for long enough to eat us. Polar Bear's top out at around 25MPH but they can sustain that long enough that the safe distance is around 1/2 mile. Brown Bear's are worse making running a bad idea.
Endurance hunting is far more effective in very high temperatures so it's use as likely limited.
Humans are group animals. Try and stalk an individual wolf in a pack as an individual (even with a rifle) and let me know how it goes. You'd be lucky to live and tell the tale. Humans are the same. Getting the better of an individual human ... so easy it's hardly worth mentioning. Same with the wolf. Doing the same in a group of 100 humans, even a single individual in that group ? You won't survive the attempt.
In all animals strategies work together to establish a desired outcome. Human strength does not come from intelligence, intelligence is simply what allows us to coordinate in large groups. The actual strength comes from the large groups.
Reminded me of a video that depicts thousands of African tribesman and their dogs on a mass hunt. It's awful to watch but it gives you an idea of how our ancestors hunted thousands and tens of thousands of years ago.

That's for modern humans. Bone density studies of humans ~10,000 years ago suggest our muscles were much stronger.

Again, it's heart wrenching to watch them take down elephants and the like, but if you're still interested: https://www.youtube.com/watch?v=ipn5rSQ2PY4
