Know the venue before you plan the workout
Oasis Sports Centre is a central London option beyond Fitzrovia, in Covent Garden. The operator lists the address as 32 Endell Street, with the main entrance on High Holborn. It has a 25-metre indoor pool; its swimming page lists a 27.5-metre heated outdoor pool with year-round swimming.
This is not an open-water swimming recommendation. Nor does “year-round” mean that every pool or session is available whenever you arrive. Check the current timetable, notices, booking conditions and entry point directly with Better. We have not reserved or verified a particular bookable slot for you.
The operator's changing-room notice, checked on 28 October, still describes work on the female changing rooms and an expected mid-November opening. It lists temporary outdoor changing cubicles and unisex showers during the work. Confirm the arrangements you need before booking; that expected date is not proof of completion.
Allow time for the full journey, changing and returning to your next commitment. Do not turn a one-hour break into a claimed one-hour swim. Exact travel times depend on your starting point and route; there is no fixed walking-time promise here.
Choose the session type first
The operator distinguishes Swim for Fitness from Swim for All and offers lessons. Choose according to your ability and the session rules, rather than assuming every booking permits the same activity.
| Your immediate task | What to check before booking |
|---|---|
| You want to swim lengths and are already confident doing so | The Swim for Fitness timetable, pool, lane arrangements and rules |
| You want a general leisure swim | The current Swim for All details, including which pool the booking covers |
| You need to learn or rebuild water confidence | Ask the operator about suitable lessons; this article is not swimming instruction |
Better advises advance booking. Summer family-session information is not a reliable timetable for an autumn lane session. Confirm the session you intend to use, not just the centre's general opening hours.
The useful arithmetic: lengths are not a standard unit
Worked example, not a workout prescription:
- Twenty lengths of a 25 m pool cover 500 m.
- Twenty lengths of a 27.5 m pool cover 550 m.
- The difference is 50 m, or 10% of the first distance.
That calculation does not show that one swimmer worked 10% harder or burned 10% more energy. Stroke, rests, pace and technique also differ. It shows why a record containing only “20 lengths” can mislead your next decision.
For a useful comparison, record the pool length, total distance, approximate swimming time, rests and how the session felt. If you change pools or spend more time waiting, note that too. Do not judge progress from a faster total visit when the actual swimming changed.
A completed swim record—and what it tells you
Hypothetical example for a capable adult swimmer. These numbers illustrate record-keeping; they are not a recommended session.
| Record | Visit A | Visit B |
|---|---|---|
| Pool | Indoor, 25 m | Outdoor, 27.5 m |
| Lengths and distance | 20 lengths, 500 m | 20 lengths, 550 m |
| Approximate time actually swimming | 15 minutes | 16 minutes 30 seconds |
| Total rests | 5 minutes | 5 minutes |
| Swimming plus rests | 20 minutes | 21 minutes 30 seconds |
| Stroke and effort notes | Front crawl; comfortable, controlled | Front crawl; felt harder towards the end |
| Conditions | No waiting recorded | Two pauses to let another swimmer pass, included in rests |
Both visits average three minutes of swimming time per 100 m. Visit B took longer because the recorded distance was greater, yet the swimmer also reported more difficulty. The arithmetic alone cannot tell us why.
What you can compare: recorded distance, swimming time per 100 m, total rests and the swimmer’s own effort notes. Keep the timing method consistent; rounded estimates are not precise performance tests.
What you cannot conclude: that the longer visit shows worse fitness, that equal average pace means equal effort, or that one pool caused a change. Temperature, turns, technique and lane conditions can differ. These two invented visits establish no training effect.
For the next visit, the practical decision is to record the same fields and review whether the chosen session still fits the purpose—not automatically add more lengths.
Give swimming a clear place in the week
Swimming can be demanding. It is not automatically a recovery session because it takes place in water. NHS guidance for adults aged 19–64 lists swimming among vigorous activities and recommends strengthening major muscle groups on at least two days each week. Your actual effort and ability matter; the venue name does not classify the session for you.
If your main goal is strength, decide what the swim is for before adding it. If the goal is improving your swimming, seek suitable swimming instruction rather than expecting gym strength alone to solve a stroke problem. To decide which sessions take priority and where demanding work fits, use our guide to combining strength and cardio.
Do not add maximal efforts, underwater distance challenges or breath-holding to make the visit feel more productive. Follow the pool's rules and lifeguard directions. If you have not exercised for some time, or have medical concerns, the NHS advises speaking with your GP first.
Take this observation card to your first planned visit
For an adult who can already swim safely in the chosen session, record:
- Before: What is the purpose? Which session and pool have I booked?
- During: What distance did I actually swim, with what rests? Were lane conditions suitable?
- After: Did the visit fit the available time? What should I repeat or change next time?
These notes help you plan the next visit. They do not establish a diagnosis, ideal training dose or a guaranteed result.
If you prefer court sport, our Regent's Park tennis-session guide helps you choose a workable court booking and leave time to prepare. If you need help fitting strength work around your chosen sport, bring your activity record to Tempo personal training, and check our Fitzrovia studio location.
