I'm writing that article today. Broadly, you're going to have three loading days (T, Th, Sa) and back-to-back easy days (Sun/Mon). That the bare bones.

The number of key sessions will depend on athlete level. It will range from 2 on each of the loading days to 2 (total) per week. Developing athletes will need to be careful with their use of intensity. All athletes will need strict intensity control.

Triathletes will do best focusing on endurance for the "X-day" (as defined by Bakken), rather than using Zones 4, 5 and 6, which are non-specific. As the goal event approaches, Saturday will shift into a race simulation workout.

It's similar to what US-based elites use. The difference between elites and the rest of us is they will flex their week based on recovery and use endurance days as well as low intensity frequency sessions scattered across the week. That's how they do so much volume compared to the rest of us. Their open schedule enables them to recover with supplemental easy volume. Easy for many pros is often quite a good pace. They are impressive humans.

You're likely to find you need to be a top amateur to handle T/Th being double tempo days. That said, if we get the intensity control right, and use a moderate dose main sets, then anybody can use double tempo workouts. At its most simple, it's a normal tempo main set that's split in half with recovery between. It is the dose and intensity targets that trip people up - not the protocol itself.

Specific to your question: I like to focus on one thing at a time. So if I'm working Tempo into my program it will be swim, bike OR run. That said, I use what the Nordics call priming workouts. For example, if I am focusing on bike tempo then I might do an early morning run that ends with a quickness set. Alternatively, I use a morning priming swim to set up a key run in the afternoon. Easy cycling is mixed into my program (most days) for supplemental volume.

As a triathlete: (1) endurance training comes first; (2) don't screw up next week, or the next key session; (3) skew all errors down and to the left.

Long term greedy for the win.

A deeper dive, with week examples by athlete type, to come.
