In Juvenis B swimming, slower times are often normal as the body changes and the training load rises. Watch tiredness and lost interest, and ask which championship is the main target. > **Idea in Brief** > - **Backward times can be normal here.** Juvenis B often brings more work while the clock stays flat. > - **There are two championship chances.** Spring has one qualifying set; summer has another. > - **Watch the swimmer, not the hundredths.** Tiredness and lost interest tell you more than last season’s times. You’re sitting in the stands after another meet, with last season’s times open on your phone. The work has gone up, but the clock has moved back. In Juvenis B, this can happen without meaning something is wrong. Bodies at this age often change faster than a stroke can keep up, so [a plateau can fill an entire época desportiva (sports season)](https://swimtrack.ai/blog/the-plateau-year) without a best time. The Federação Portuguesa de Natação (FPN) fixes the escalão (age category) by birth year for the whole season. A birthday during the season changes nothing. For 2026/27, the FPN’s regulamento (rules document) sets Juvenis B as the 2012 birth year. The Juvenis calendar has three clear markers. The Torneio Zonal de Juvenis runs from 4 to 6 December 2026, in Bragança for the north and Leiria for the south. The Campeonato Nacional de Juvenis follows from 2 to 4 April 2027 in Oeiras, at Jamor. The summer Campeonato Nacional de Juvenis, Juniores e Seniores runs from 29 July to 1 August 2027 in Coimbra. The regulation names the summer meet as piscina longa (a 50-metre pool). For the other two, each meet’s own regulamento states the pool. TAC means Tempo de Acesso à Competição, the qualifying time. Mínimos is the everyday word for it. The spring championship has its own TAC set and date window; the summer championship has another. A time must come from an official meet before entry and meet the limit for that pool. Pool sizes are not converted. You can check the [FPN qualifying times by escalão and prova (event)](https://swimtrack.ai/time-standards/portugal-fpn-tac/). For many swimmers, the coach treats spring as a check and builds the plan around the summer chance. At the same time, the training week and expectations often rise. Morning sessions may appear. [What counts as a normal number of practices](https://swimtrack.ai/blog/how-many-practices-is-normal) depends on age and the coach’s plan. At home, [sleep is often the biggest lever you can protect](https://swimtrack.ai/blog/sleep-the-biggest-lever). Last season’s times are a poor weekly baseline here. Put repeated tiredness and fading interest ahead of lost hundredths, and bring either pattern to the coach. --- ### Share it with your swimmer Keep the conversation on how the season feels: - **Under 12 (you're driving).** *“This year may take time. Tell me how the week feels.”* This gives a younger swimmer one simple check-in. - **12–15 (sharing the wheel).** *“Are you tired, losing interest, or still keen to train?”* This gives them clear words for the week. - **16+ (they're driving).** *“What do you want me to notice, and what stays with your coach?”* This respects their growing ownership. ### Stay aligned with your coach The coach sets the training load, chooses each prova, handles entries, and decides how April and July fit the plan. You watch tiredness and interest at home, then ask, *“Is the main target the 2–4 April championship or the 29 July–1 August championship, and what should I watch at home?”* That keeps the plan with the coach. ### Keep exploring - [The plateau year](https://swimtrack.ai/blog/the-plateau-year) — A plateau can last a full sports season. - [Sleep: the biggest lever](https://swimtrack.ai/blog/sleep-the-biggest-lever) — Sleep often becomes the main lever you can protect at home. - [How many practices is normal?](https://swimtrack.ai/blog/how-many-practices-is-normal) — Practice counts depend on age and the coach’s plan. - [Best time, not placement](https://swimtrack.ai/blog/best-time-not-placement) — Personal progress can matter more than meet placement. - [FPN qualifying times](https://swimtrack.ai/time-standards/portugal-fpn-tac/) — Check TAC by escalão, prova, and pool size. ## Related reading - [Swimming plateau: why times stall and when to ask the coach](https://swimtrack.ai/blog/the-plateau-year/) - [How much sleep do swimmers need, and why does it matter?](https://swimtrack.ai/blog/sleep-the-biggest-lever/) - [How many swim practices a week are normal for each age?](https://swimtrack.ai/blog/how-many-practices-is-normal/) --- SwimTrack — https://swimtrack.ai HTML version of this page: https://swimtrack.ai/blog/juvenis-b-the-body-changes/
