Training analysis for runners

Understand how you train.

Upload your watch activities and LT2 tells you how fit you are, what works for you and what you can achieve. We start with running; your other sports count too.

What each week works on: base, threshold or speed.

Load 37.2 CTL TSB +6.5 · Optimal load

Your fitness and fatigue from the load of all your sports: whether to push or to rest.

VO2max 56.5 ml/kg/min +3%

Your VO₂max estimated from your training, with no lab test.

Planning

Plan and reach your goal.

Put your sessions on the calendar, move them when the week changes and see how your load builds up to race day.

  • Drag a session and your load is recalculated instantly.

For coaches

Your whole group at a glance.

With Team you see what’s waiting for review, each week’s compliance and who needs attention, and you plan for every athlete.

  • What’s waiting for review comes first: every session your athletes do, ready for your comment.
  • Each athlete’s compliance, day by day and week by week.
  • Who needs attention: overload, inactivity or a race coming up.
  • Plan each athlete on their calendar, and we’ll let you know when they upload a workout.

The free team includes up to 3 athletes; we don’t offer larger teams yet. Sign in, request it in Settings › Team and we’ll let you know as soon as it’s ready.

Frequently asked questions

What people usually ask

Do I need a watch with a heart rate monitor?

With heart rate the analysis is much more complete, but without it you still get volume, paces, calendar and planning.

What do you do with my activities?

We only use them to calculate your analysis. You can delete them, or your account, whenever you like.

Does it work with Garmin, Coros, Polar, Suunto or Apple Watch?

Yes: export the FIT, GPX or TCX files from your watch's app and upload them. Apple Watch sync will come with the iPhone app.

Is it useful if I don’t only run?

Your cycling, swimming or strength sessions count towards your load and calendar. Sport-specific analysis starts with running and will grow one sport at a time.

Do I have to install anything?

No. It works in the browser and you can add it to your phone’s home screen like an app.

I coach a group. Is it for me?

Yes. Request a free team in Settings › Team: we review it and let you know. It includes up to 3 athletes; we don’t offer larger teams yet. Your athletes join with your invitation and you see their week, what’s waiting for review and their compliance.
