Under the Swim, Bike and Run headers are three columns - Rank, Time and Pace in each case.  I'll briefly explain each, moving from left to right.

Swim:

Rank: This is your place in the swim.  A 20 would, for example, mean you had the 20th fastest swim.

Pace: This is the tricky one.  It looks to be the time it takes to swim one mile at the indicated time, but there seems to be an error of 3% or so.

Bike:

Rank: This is your ranking after 2 events, the swim and bike, not your bike ranking.

Pace:  The number shown is the time it takes you to cover one mile.  A more common way to measure bike speed is in mph, miles per hour.  To calculate, divide the course length by the time it took you to finish.  For example, let's calculate the winner's pace: First, convert the time to a decimal format: 26:11.9  = 26.198 minutes.  Convert that to hours, and divide: 10/.4366 = 22.9 mph.  But note that the bike splits have both transitions, swim-to-bike and bike-to-run, added in.  Sometimes they are broken out separately.  If we pulled T1 and T2 from the winner's bike split, we would see a bike time of around 25 minutes, which is 24 mph.  John Deshotel is one of the country's top amateur triathletes, and he usually bikes around 25 mph in a sprint triathlon.  He missed a turn in this race, or his bike split would have been probably 30 seconds faster.

Run:

Rank: Overall finishing position

Pace: This is how fast you ran per mile.
