It's about 50 times as fast as a Bull.
In other words, the speed of a Bull is 0.02 times 1.03 mach.(for animals involved in the Running of the Bulls, a.k.a. Encierro, San Fermin, Pamplona, Spain) (herd average speed)
The herd of the annual Encierro in Pamplona, Spain runs at an average speed of 0.02 mach. The Encierro is run annually from July 7th through July 14th and involves 42 bulls, 77 oxen, and an estimated 17,000 runners over the course of the event.
It's about one-one-hundredth as fast as a Meteor.
In other words, 1.03 mach is 0.0081 times the speed of a Meteor, and the speed of a Meteor is 120 times that amount.(formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")
Small meteoroids enter the Earth's atmosphere at speeds between 34 mach and 220 mach, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 8.40 mach.
It's about 150 times as fast as a Crocodile.

Setting a world record, Michael Phelps swam the 200 m freestyle in 1:42.96 for an average speed of 0.0058588 mach. Phelps would go on to win nine gold medals individually in the 2008 Olympics - more than all but eight of the competing nations.
It's about 250 times as fast as Walking Pedestrians (in Manhattan).
In other words, the speed of Walking Pedestrians (in Manhattan) is 0.0038 times 1.03 mach.(Manhattan; average speed; 8,978 person-sample)
A 2006 Study by the New York City Department of City Planning found that pedestrians in that city walk at an average rate of 0.0039 mach. Pedestrians wearing headphones, the study went on to find, walk at a slightly faster 0.0043 mach
It's about one-three-hundredth as fast as a bolt of Lightning.
In other words, 1.03 mach is 0.0035 times the speed of a bolt of Lightning, and the speed of a bolt of Lightning is 290 times that amount.(atmospheric electrical discharge)
A bolt of lightning can travel at up to 290 mach when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about 700 times as fast as an Iceberg.
In other words, the speed of an Iceberg is 0.001 times 1.03 mach.(a.k.a. Berg) (Newfoundland iceberg average)
Moved by ocean currents and wind, icebergs can drift at speeds of about 0.002 mach. The largest iceberg ever recorded was a found near Baffin Island, Nunavut and was estimated to be nine billion metric tons.
