Getting comfortably under 9 hrs (8:49) is kan fast for a non full timer.
I posted the Qatar Airways Hamburg one for Women last Sunday. Kat Matthews was in there, 8:05. (she did T100 Singapore last year also)
Aaroniseverything also fast fella, actually his run leg was faster than Ben. He mentioned he biked too conservatively, his vlog got scenes where he was like just enjoying himself easy ride and laughing one.

And of coz his swimming also not strong discipline.
See how he does for Desaru 70.3.....he is getting siaolang fast .
