Winter Season 2026 / 27 · Indoor, Zurich

The winter decides
next summer.

Coached indoor tennis from October to March. Privately, or in a group of up to four — adults and juniors, grouped by level, in halls across the Zurich area.

Summer is played.
Winter is built.

Nobody changes a serve in July. The season is too full of matches, and a technical change that is half finished under pressure is worse than no change at all. Winter is the only stretch of the year long enough and quiet enough to rebuild something and let it set.

Which is why the players who move up a level between one summer and the next almost always did the work between October and March — and the ones who stay exactly where they were took the winter off.

Flexible on the hall.
Not on the standard.

The seasonOctober to the end of March. Take the whole season or a block inside it.
The hallIndoor courts across the Zürich area. I place you where the times actually work for your week, rather than where a club timetable says you must be.
The courtYou book it and the hall invoices you directly. My invoice covers coaching only. If you are already a member somewhere, your court is often covered.
The groupAlone, or up to four. Groups are formed by level, so nobody is held up and nobody is held back. Bring your own players or I will place you.
The blockTen or twenty hours holds your weekly slot for the season. Or pay by the hour if your winter is unpredictable.
BookingSessions are booked, moved and tracked in the AG Performance app.
CancellationsMove or cancel up to 24 hours before, free. Inside 24 hours the session is charged — the coaching hour is already committed.

From CHF 50 an hour,
in a group of four.

Per person, in Swiss francs, coaching only. One card for every player — adults, performance players and juniors pay the same. What moves the price is how many of you are on court, and a group is where a technical change gets tested under pressure.

Blocks save five per cent over ten hours and ten per cent over twenty, and hold your weekly slot for the season. Groups are formed by age and level — juniors train with juniors. Court hire is not included and is invoiced to you by the hall. Invoiced in Swiss francs; 24-hour cancellation applies.

Existing clients hold most of the weekly hours, so what is left goes in the order it is asked for. Send this and I come back personally within 48 hours with the times that are actually free and what they cost.

Everything you might ask.

No — the rates cover coaching only. You book the indoor court and the hall invoices you directly. If you are a member somewhere with indoor courts, your court is often already covered, which is why the price is quoted this way rather than bundled.

October through to the end of March. You can start later — the block simply runs from whenever your first session is.

No. Bring your own players if you have them, or tell me your level and I will place you. Groups are formed by level, so nobody spends the hour waiting for a ball they cannot return and nobody is held back.

Two different products. The season rate is coaching only, at a hall, where you hold the court — it is the best value if you play regularly. The concierge private is all-in and year-round: I come to your club, the court is arranged, and it fits around a schedule that will not survive a fixed weekly slot.

Move or cancel up to 24 hours before at no charge. Inside 24 hours the session is charged, because the coaching hour is committed and cannot be resold at that notice.

Yes, at junior rates. Juniors are grouped by age as well as level — the drills, the pace and the way things are explained all change with both.

Before the winter, and after it.

Autumn camps

Five mornings on court in the autumn holidays, juniors and adults, TC Ried Wollerau. The week before the indoor season starts.

Tennis & Performance Retreat

Six days at the Rafa Nadal Tennis Centre, Sani Resort, Greece. 24–30 April 2027, twenty places.

Winter slots go in the order they are asked for.
