Training for a triathlon requires a lot of hard work- especially when it comes to figuring out how distances relate in the pool and open water. Check out this handy swim distance chart to help convert distances for races and training in the pool.

Swim Distance for Racing and Training
25 Yard Pool
1 Length = 25 Yards (From Wall to Wall)
2 Lengths = 50 Yards
4 Lengths = 100 Yards
1/4 Mile = about 500 Yards = 20 Lengths
1/2 Mile = about 800 Yards = 32 Lengths
1 Mile = about 1,700 Yards = 68 Lengths
1.2 Miles = about 2,000 Yards = 80 Lengths
2.4 Miles = about 4,000 Yards = 160 Lengths
50 Meter Pool
1 Length = 50 Meters
2 Lengths = 100 Meters
1/4 Mile = about 400 Meters = 8 Lengths
1/2 Mile = about 800 Meters = 16 Lengths
1 Mile = about 1,500 Meters = 30 Lengths
1.2 Miles = about 2,000 Meters = 40 Lengths
2.4 Miles = about 4,000 Meters = 80 Lengths
