While I am a swimmer and would love to see a longer swim leg,
we should remember how the distances were arrived at. The
distances were selected because they were standard distances for
1500 meters is the common distance swim
40K is a common bike time trial
10K is the distance race in running
Hence the international distance was arrived at. Fairness or equality
were not considered.
Of course, for the Ironman we have
2.4 miles the Waikiki rough water swim
112 miles the bike race around Oahu
26.2 miles the Honolulu Marathon
The sport was not conceived or designed to be fair and equal. The
standard distances from the three sports were simply jammed together.
Accept it and live with it. If you are really a good swimmer try some
open water swims.
