Performance training that adapts to a busy life

A plan that bends around your week, not the other way round.

It reads your night before it plans your day.

Meetings run late, nights run short, the weather turns and work takes you away. nustride reads your sleep, HRV and the training you've actually done, keeps the hard sessions that build fitness, and protects the key session of the week, so you still arrive at race day ready. Every change is proposed, explained, and yours to confirm.

The intelligence layer

Watch a week rearrange itself.

A plan written on Sunday rarely survives to Friday. Here is one week, and what the coach does each time life gets in the way. The aim never changes: the sessions that make you faster still happen, and the week's training still lands where it should.

What happened

The plan, as written on Sunday.

Five sessions, about 5 hours, with Saturday's long run as the key session of the week.

The week's training load100%
of what the plan set out to do
A plan that moves with you

The coach proposes. You decide.

When your readings, the weather or a missed session say the week should change, the coach suggests one change and says why. Nothing moves until you confirm it.

Proposal for Thursday

Move Thursday's hill reps to Friday and run easy instead.

HRV has been under your normal for three mornings, and Wednesday's long ride was harder than planned.

Heat on the day

At 26°C your pace band eases by 2.4%.

10°C18°C26°C33°C40°C

From 18°C the coach slows your target pace, up to 6.5%. From 33°C it drops pace altogether and coaches on heart rate and effort. The figures on this page are examples.

Every number has a source

A morning call you can check, line by line.

The call is written overnight from what your watch and phone sent. Each figure in it carries a mark that opens the reading behind it, with its source and its age. If a number can't be traced, it doesn't go in.

Amber only ever means one thing: a reading that is old or missing. The coach says so, and never fills the gap with a guess.

After every activity

A straight verdict on what you did.

Each session is judged against the plan: length first, then your own effort, then heart rate. Eight outcomes, and the coach shows the evidence for the one it picked.

An event, getting fitter, feeling better day to day, making it a habit, or coming back from a break.

2

Where are you now?

Just starting, training without a plan, mid-plan, or coming back. This sets where the coach starts.
