 15 miles in 10 ft/s.
 Average time for light to travel from the Sun to the Earth.
Pace and time
Examples of how pace and time are used for calculating distance (and also converting to other pace units).
 2 hours running in 7:30 minutes per mile.
 50 minutes rowing in 3:15 per 500 m split.
 Driving 4.5 hours in 80 kilometers per hour.
Target split times
Examples of how target split times can be calculated from various sources of information.
 Suppose you plan to run 5 km with a target pace of 4:30 /km. Then you fill in the pace (4:30 per km) and 5 kilometers in the distance field. You also define kilometers in the split distance in dropdown. Push the calculate/convert button and you can read the target split times (for 1, 2, 3, 4 and 5 km) in the table below the calculator. You also see the target goal time, which is 22:30 in this example.

Fill in distance 10000 meters, split distance in 400m laps and 26:17.53 as time. Then you will see the target split times for 1, 2, 3, ..., 24 and 25 laps, that you'll have to beat for breaking Kenenisa Bekele's world record.
If you are a Swede you can first try to beat Jonny Danielson's Swedish record of 27:55.74 or Sarah Lahti's Swedish record of 31:54.87.  The current Marathon world records:
