So it looks like we've got some world class triathletes who could a) jump in local 10Ks and run really well, probably win (sub 31) and; b) run with world class runners and get smoked (sub 31). I'd bet the same thing would happen if they got into local bike races (do well, maybe dominate) vs. professional bike races (get smoked). Same with swimming ...
Maybe that's why they're world class triathletes ... (or maybe not) ...
