And you are using one of the fastest Ultraman swimmers as an example of what? The Hawaii swim favours pure swimmers because of the currents and Jordan took an hour or so off his run PB that day which surprised everyone.Very few have swum in the time frame that Jordan does.He is one of the outliers and history shows the winners of the first eight or so runnings of Ultraman Canada was won by the person who won the swim.I did it twice and that has been repeated again and again and again.

The difference now is,as more people move to Ultra-triathlons the more they are training for longer swims and the average swim pace is getting faster.Last year in Ultra520k Canada the slowest time was 4:24 with only three swimming over 4hrs.Back in my day that sort of field was unheard of as most were in the 4-6hr range.
