Who it is for

Runners

From a flat 10k to a mountain ultra. Downhill durability and fatigue resistance for the back half.

Cyclists

Road, gravel, climbs and time trials. Your power curve and the climbs on your course set the work.

Triathletes

Swim, bike and run planned as one season. Transitions and bricks get real sessions.

Duathletes

Run, bike, run, with the second run trained as its own demand.

What you get

Seven surfaces, one loop, in the order they happen to you.

Event analyzer

Upload the course and read what the day will demand of you.

The Event analyzer on IRONMAN Lanzarote. The bike leg course is drawn on the island map under a typical weather chip of 19 degrees and a 35 kilometre an hour north wind, beside an estimated total time of 14 hours 26 minutes with 2,334 metres of climbing and the bike leg average speed and power target. The leg is scored across twelve demand dimensions, from aerobic endurance at 95 to sprint power at 10, above a hill profile where hovering the biggest climb shows its gradient.

Focus Lab

Your history is the supply, the event is the demand. We find the gaps.

The Focus Lab for a full distance triathlon bike leg on a wide desktop window. The first gap, aerobic endurance, reads 53 for the athlete against a course demand of 100 and a target of 100, and its reason is open beneath it: what the dimension means, why the course asks for it, how the target was set, how the athlete was estimated, and the sessions that train it, with the next gap, muscular endurance, below.

Season planner

Those gaps become a season, laid out backwards from race day.

The Season page on its Blocks and focus tab. A grid of the three sports across the blocks of the season shows the focus of each block in colour, from aerobic endurance through threshold and muscular endurance to the peak and the race at the end. The current block is open: aerobic endurance leads for the swim and threshold durability for the bike and the run, each with its supporting dimensions, above the list of the blocks still to come.

Calendar and workout planning engine

Press Plan my season and every week fills with sessions that train its focus.

The Calendar on the current training week, Monday 5 to Sunday 11 October, beside its summary. Key sessions carry a star and a strip that draws their intervals, each marked done or missed and tagged with the capacity it trains, such as threshold capacity, movement skill or aerobic base. The summary gives compliance, completed load and time, the Focus Lab focus for the bike and the run, and fitness, fatigue and readiness, with the next week planned below.

Performance

Curves, efficiency, decoupling and durability, measured from your own efforts.

The Performance page on its Performance markers tab. The efficiency factor of a run and a bike over three months, each with its current value, its change, its decoupling and a verdict, with the readings plotted against a 42 day trend and a hovered bike reading of 1.29 watts per beat against a trend of 1.23. The fatigue resistance cards begin below.

Workout library

Vetted structures with a stated purpose, an approved dose and a stop rule.

The Workout library filtered to cruise intervals, 20 of its 430 sessions drawn as their interval shapes, with the Cruise Intervals 6 minute session opened. The session shows four threshold blocks between two steady blocks, its zone times, its purpose, its focus, the phases it suits and its progression: start the season at 12 minutes in total and build by repetitions toward 30 to 50 minutes.

AI coach
