IIRC, it's 43.45 km/h (Donovan Bailey, OG in Atlanta, 100m final)

Well, the top atletes are able to run in average speed of 33.3 km/h
at 400m (WR 43.18 s.) and 28.4 km/h. at 800m (WR 1:41.11 min.). An
"average" human would run much more slowly, though.

AFAIK, nobody without a further training can reach over 34 km/h.

Right. Donovan Bailey, Maurice Greene and Tim Montgomery, perhaps?
Me? My PB at 100m is 10.7 s., my top speed is around 40.5 km/h. ;o)

One step of T. rex measured some 3.5-4 meters (rather than 5), IIRC?

I'm walking faster than that, most of the time over 2 m/s.(7.2 km/h).
BTW, I've read somewhere, that _A. huinculensis_ (and any 50+ tons
sauropod for that matter) probably wasn't able to walk faster than
just 6 km/h? thanks, Vlad
