Sprint triathlon training
Free Sprint Triathlon Training Plan
A sprint triathlon is a 750 m swim, a 20 km bike and a 5 km run. It is the best first triathlon and a sharp, fast race for experienced athletes. The training fits around a normal week: two or three sessions per sport, plus a few bricks.

How a sprint triathlon plan is structured
Most athletes need 8 to 12 weeks. A typical week has two or three swims, two or three rides and two or three runs, though beginners can start with two of each. The first weeks build comfort and technique in each sport, the middle weeks add one quality session per sport and weekly bricks, and the last week tapers. Roughly 80 percent of training stays easy, and weekly hours rise gradually with a lighter week every three or four.
Put your time where your weakest sport is
Time spent per sport should follow where you lose the most, not what you enjoy. For many beginners the swim is the limiter, and two or three short technique-focused swims a week do more than one long one. Strong runners often gain most on the bike, which is also the longest leg. Keep your strongest sport ticking over with one quality session and one easy session.
Bricks: running off the bike
A brick is a bike session followed immediately by a run. The first minutes of running after cycling feel heavy and uncoordinated for everyone, and bricks teach your legs to adapt quickly. For a sprint, 30 to 45 minutes on the bike followed by 10 to 15 minutes of running is plenty. One brick a week in the second half of the plan is enough; the run should start controlled, not fast.
Practise open water and transitions
If your race is in open water, get in open water before race day, ideally with a group or lifeguard and a tow float. Practise sighting every six to nine strokes, swimming in a wetsuit if you will race in one, and starting among other swimmers. Rehearse transitions at home too: lay out your kit, practise removing the wetsuit and mounting the bike. A smooth transition saves more time than a week of training.
Key sessions and the taper
Useful key sessions: in the pool, 8 × 50 to 100 m at a strong effort with short rests; on the bike, 4 × 5 minutes hard with 3 minutes easy; on the run, 5 × 3 minutes at 5K effort. In the final 5 to 7 days, cut volume by about half and keep a few short race-pace efforts in each sport. Arrive rested; a sprint rewards freshness more than any last-minute session.
A sample week
A mid-plan week of about 5 to 6 hours. With fewer hours, keep the brick and one session per sport.
- Mon
- Rest
- Tue
- Swim, 40 min: drills, then 8 × 100 m strong with 20 s rest
- Wed
- Run, 40 min: 5 × 3 min at 5K effort, 2 min easy between
- Thu
- Bike, 50 min: 4 × 5 min hard, 3 min easy between
- Fri
- Swim, 30 min easy technique, open water if you can
- Sat
- Brick: 45 min bike steady, straight into 15 min run, first 5 min relaxed
- Sun
- Easy run, 40 min, or easy ride, 60 min
The mistake first-time triathletes make
Training only the sport you already like. Runners run, swimmers swim, and the race exposes the gap. A second common one is skipping open-water practice, then panicking in the first 200 metres of a crowded swim. Balance the week toward your weakest leg and rehearse the swim start before race day.
Common questions
How long does it take to train for a sprint triathlon?
Eight to twelve weeks for most people who can already swim, ride and run a little. Complete beginners in one sport should allow extra time to build comfort there.
How many hours a week do I need?
Four to seven hours is typical. Beginners can finish comfortably on about four hours a week if the time is spread across all three sports.
Do I need a wetsuit or a road bike?
Neither is required for most sprint races. Check your event's wetsuit rules, which depend on water temperature. Any safe, working bike will do for a first race.
Is the triathlon plan free?
Yes. AthleteSpace is free with no credit card, and the builder shows your sprint plan without an account.
