I am 13 and running with freshmen and sophmores in my first ever indoor race got 49 seconds. Hope it helps!
With stock gearing (13:38) the 300ex tops out at 58 mph.
13 mph = 20.9 kph
speed = distance/time = 34 miles / 13 hr = 2 8/13 mph ≈ 2.62 mph
13 or lower is good
I don't know, but my time was 13 seconds
60/13 = 4.615 mph (rounded)
the average time for a 13-14 year old boy to run the 100 meter is about 15 seconds if you are athletic 20 seconds for a non athletic boy
The standard for a 13 year old girl is around 12-13 seconds. It also depends on how good that girl is. I am in Track and Field and I do 100 meter sprints. My fastest time is 13.54 and I am 13. Most girls get around that time.
approx. 13 seconds @ 102 mph
