You set the goal. You do the workout. NextSession takes care of the rest.
Your coach fits the plan to your week, reworks it when life moves, tells you how each workout went and what it means for the next, and puts every session on your calendar and watch.

You picked a half, found a plan and fit it around work and family. Then the week moves: a trip, a late night, a sick kid. The plan doesn't.A charity place in your first marathon: a fixed date, money pledged and eighteen weeks of training you have never done. Then travel, a wedding, a cold, and nobody to ask what to change.A 100-mile ride on the calendar and a structured plan for the trainer and the road. Then weather, daylight and work decide which days you actually ride.Three sports, a pool timetable and a job. A 70.3 plan has more pieces to move than any other, and one missed swim knocks into the bike and the run.
Built for the athlete who:
Wants structure
A real plan with key sessions and targets, not a list of random workouts.
Doesn't want the admin
No rebuilding the week by hand every time a meeting, a trip or a bad night moves it.
Wants every session to count
Every session has a purpose, optimized for results. They just do the workout.
