I've co-run Ultimate Fitness Holiday out of Cala San Vicente since 2021, handling guest bookings and coordinating the personal trainers and coaches who rent our venue for their own retreats. Most of them aren't full-time retreat operators — they're PTs who run a handful of weeks a year alongside their studio or one-to-one work, and the income they generate is substantial enough to shift their annual picture completely.
Why retreats work as side income for busy trainers
The maths is simple. If you're charging £40–£60 per session in London or Manchester, you need twenty sessions a week to clear £4,000 monthly before tax and overheads. A single week-long retreat with ten guests at €1,200 each generates €12,000 in gross revenue. Your costs — accommodation, food, transfers, venue hire — might run €6,000–€7,000 depending on how you structure it. You walk away with €5,000–€6,000 profit for one week's work, often more than a full month of sessions at home.
The side income model works because you're batching. Instead of spreading thirty individual clients across thirty separate hours, you're delivering group programming to ten people over seven days. The intensity is higher — you're on from breakfast through evening sessions — but the revenue per unit of your time is three to four times what you'd earn hourly back home.
Most of the PTs who use our Cala San Vicente venue run two or three retreats a year. That's two or three weeks of full-time effort, plus the marketing and booking admin spread across the preceding months. It's not passive revenue — no retreat income is truly passive — but it is part-time in the sense that it doesn't require you to leave your regular client base or rent commercial space year-round.
What our venue in Cala San Vicente actually costs and includes
We have eight en-suite rooms on site, which means your group size caps at sixteen if everyone doubles up, or eight if you're running single occupancy. Most trainers bring eight to twelve guests. The venue rate covers the accommodation, breakfast and lunch from our on-site restaurant, and access to the outdoor training area and equipment — barbells, kettlebells, TRX, mats, resistance bands. You're not hiring a sports hall separately or negotiating with three different suppliers.
Full board (breakfast, lunch, dinner) runs higher per person per day than half board, but it simplifies your logistics and removes one variable your guests have to think about. We're walking distance to the beach in Cala San Vicente, so you can programme beach runs or swimming without needing to organise transport. The Tramuntana mountains are directly behind the bay — we've had trainers take groups up to the Castell del Rei trail (steep, technical, about 90 minutes up) or the gentler coastal path towards Cala Molins.
Palma airport (PMI) is roughly 70km away, about an hour by road. Most organisers either arrange a private transfer through a local company (we can introduce you to the one we use) or tell guests to share taxis. A private minibus for twelve people runs around €150–€180 each way, so €25–€30 per person return. Guests booking their own taxis usually pay €80–€100 for the whole vehicle depending on time of day, and they split it if they coordinate.
April–May and September–October deliver the best margins
July and August are peak season in Mallorca. Flights from the UK cost more, the island is busier, and the daytime heat makes outdoor training before 8am or after 6pm the only comfortable windows. Shoulder season — April, May, September, October — gives you warm weather without the peak pricing or the crowds. April and May are especially good: you get 20–24°C daytime temperatures, the hills are still green, and flight prices from London or Manchester are half what they'll be in July.
Your venue costs stay relatively flat across those months, but your guests' flight and transfer budgets stretch further, which means you can either lower your headline price to fill the retreat faster or hold pricing steady and improve your margin. We've had organisers run back-to-back weeks in May — the first week covering costs, the second week almost pure profit — because the guest acquisition cost per person dropped when they could offer a second date immediately.
September is the single best month we see for repeat bookings. Guests who came in May often rebook for September the same year, and trainers who ran a spring retreat will add an autumn one if the first sold well. The sea temperature is still 23–25°C through mid-October, versus 18–20°C in May, so you get better conditions for open-water sessions if that's part of your programming.
Local rhythm: the Pollença Sunday market and off-site options
Pollença town is fifteen minutes by car. The Sunday market there is the largest on the island's north coast — over 300 stalls, everything from fruit and cheese to ceramics and linens. If your retreat runs Sunday to Sunday, you can either build in a free morning and let guests explore independently, or make it a group outing. It's low-cost, photogenic, and gives people a break from structured programming.
We're also close enough to Alcúdia (20 minutes) and the Cap de Formentor viewpoint (30 minutes) that you can offer an optional half-day excursion without losing a full training day. Some organisers programme a 6am sunrise hike to Formentor, then bring the group back for breakfast at 9am and continue the day's sessions. Others leave excursions entirely optional and focus the week on training and recovery.
The marketing and booking load for a two-retreat-per-year model
If you're running two retreats a year, you need to start promoting at least four months out to give people time to book flights and arrange leave from work. That means your marketing window is roughly March through May for a September retreat, and August through October for the following April or May. You're not running year-round campaigns — you're doing two concentrated pushes, each eight to twelve weeks long.
Most of the trainers we work with use their existing email list and Instagram following. They'll post three or four times a week during the booking window, send one or two emails a week to their list, and offer an early-bird discount for the first four or five sign-ups. Once you've sold half the spots, the remainder usually fill faster because social proof kicks in and people see the retreat is actually happening.
Booking admin is where the part-time model can get messy if you don't systematise it. We handle accommodation bookings and meal planning on our end, but you're managing guest payments, deposit schedules, and travel coordination. Most organisers use a simple deposit structure: €300–€400 per person upfront (non-refundable after a certain date), then the balance due six to eight weeks before arrival. That gives you cash flow to confirm the venue and arrange transfers without fronting the full amount yourself.
Guest questions peak in the two weeks before the retreat. People want to know what to pack, whether the training is suitable for their level, what the food situation is if they're vegan or gluten-free. If you're running two retreats a year, that's four weeks total of higher-volume guest communication. The rest of the year, it's sporadic — someone asking about next year's dates, a past guest referring a friend.
Whether our Cala San Vicente venue makes sense for your model
Our setup works well if you want to focus on training and guest experience rather than logistics. You're not sourcing a separate chef, negotiating accommodation rates at three different hotels, or booking a sports facility by the hour. Everything's on site, and we handle the food, rooms, and basic equipment. That means your prep work is programming the week's sessions, marketing the retreat, and managing the bookings.
The trade-off is less flexibility on pricing structure. You're paying a per-person rate that includes accommodation and meals, so your cost base is relatively fixed. If you've got a strong enough brand to sell spots at €1,400–€1,600 per person, the margin is excellent. If your audience can only stretch to €900–€1,000, the numbers get tighter unless you're filling all sixteen beds or running longer than seven days.
We've also worked with trainers who co-host with another coach — one handling strength and conditioning, the other covering yoga or mobility — and split the revenue and workload. That model works particularly well if neither of you has a large enough list to fill eight spots solo, but together you can pull twelve to fourteen. You're halving the income per person, but you're also halving the marketing effort and the on-the-ground intensity.
If you're thinking about Mallorca and want to walk through whether our venue fits your programming, guest profile, and pricing model, get in touch. We can show you the space, talk through what's worked for other trainers in similar positions, and give you an honest view of whether the numbers make sense for the kind of side income you're after. The model works well for the right person, but it's not universal — and there's no point spending three months marketing a retreat if the economics don't stack up from the start.
