I recommend you look around in your area for other organized runs, swims and cycling events. This will help you get familiar with they process of going thru the event, how it feels racing other especially swimming and cycling and show you which event of the trialthon you need to improve.

Less is more would be my tip. Try to do more days of training rather than more intensity, and try to swim at least a couple of times a week (swimming technique gets lost very rapidly)

I find doing such long distances in a pool so boring. I much prefer open water. I’ll be doing a couple of miles in the local river tomorrow morning. I’ll probably be thinking about bitcoin then too.
