You can't compare sprint speeds like Usain Bolt's 28mph to sustained speeds like a "25-30mph gallop". Bolt can't run at 28mph for longer than 100 meters or so, a horse can gallop at 30mph for over a mile.
The current world record 1-mile run for a human is Hicham El Garroj at 3:43.13 (16.1mph), while the world record Kentucky Derby run is Secretariat (1:36.4 at the mile; 1:59.4 at 1.25 miles - 37.69mph). That is *over twice the speed* of the human. More importantly, even a not-so-great horse could run at ~20mph for a mile, which no human can possibly match.
The man vs horse race only becomes a fair matchup over a marathon-like distance of 20-24 miles... even then the human has only a very small percent chance of victory (twice over 35 years) and this is completely dependent on hot weather causing the horse to tire out. Horses are not good at handling extreme heat; this is why people in very hot climates ride camels or donkeys.
If you're considering terrain, rough terrain slows a human MUCH more dramatically than it slows a horse. Try walking through brush; it is painfully slow and you risk breaking an ankle. A horse with good shoes can move much more easily than a human. Horses can also ford shallow water much more easily than a human. The only exception is vertical terrain; a human can climb rocks and clamber up steep slopes that a horse cannot.
I was comparing them in terms of being the top speeds of each animal. Like the gallop is basically the horses sprint, but they can sprint for upwards of a mile and a half, fit/different breed horses longer. That's how I was looking at it. I think we are pretty much in the same camp, an everyday horse can beat most humans in most running situations.
Edit: I excluded bacteria because they can't run.
