Why an AI‑Adaptive Plan Beats a Static PDF

Traditional 8‑ or 12‑week schedules assume everyone starts with the same fitness, owns the same equipment, and never misses a workout. Real life—jobs, kids, travel, injury niggles—says otherwise.

Athletica plugs in two years of your historical fit‑files (runs, rides, swims and gym sessions) and builds a unique fitness and fatigue signature. Each night, the engine reads your nocturnal heart‑rate variability (HRV) and resting heart‑rate, then cross‑checks them against how hard yesterday felt (your RPE + session comment sentiment). When the signals point to rising strain, tomorrow’s plan eases back; when freshness returns, you’ll see sharper quality sessions appear.

Result? As featured in Triathlete, consistent training, better adaptation, fewer DNS‑inducing illnesses.

How the Sprint Triathlon Training Plan Evolves

Base Phase  (4‑12 weeks)

Aerobic‑engine building: Z2 rides and swims, easy aerobic runs, plus technique drills.

Single leg deadlift for HYROX strength training

Build Phase  (3‑8 weeks)

Introduce brick intervals, tempo runs and threshold swims to develop race‑specific speed and pacing skill.

Recovery Weeks

Every 3‑4 weeks the AI inserts a down‑week—reduced volume and low‑intensity drills—to absorb training and eliminate lingering fatigue.

Taper  (7‑14 days)

Sharpening sessions, open‑water familiarisation and mindset cues, leaving you fresh yet fast on the start‑line.

Dynamic length

Have only five weeks till race‑day? The AI compresses phases, prioritising the highest‑yield workouts. Starting ten months out? You’ll cycle through multiple Base‑Build blocks, each stepping volume and intensity progressively.

Single leg deadlift for HYROX strength training
Phase Typical Span* Key Sessions Goal
Base 4–12 wks Endurance Z2 rides & swims; aerobic runs Aerobic capacity
Build 3–8 wks Brick intervals; tempo runs; VO2bikes; threshold swims Race speed
Recovery 5–7 d Low‑intensity; skills drills Super‑compensation
Taper 7–14 d Sharpening bricks; open‑water swims Peak freshness

Athletica adjusts these automatically based on your fitness and time‑to‑race.

Fully customizable—swap weeks, insert an extra recovery block, or extend the base phase whenever life (or fatigue) demands.

Frequently Asked Questions

How many weeks long is this sprint‑tri plan?
The plan is as long as you need—Athletica dynamically scales from 52 weeks out all the way down to a three‑week quick‑build.

Can I start if my race is only four weeks away?
Absolutely. The AI compresses phases, emphasising quality training and race‑specific pace, while trimming volume appropriately so you arrive fresh.

What happens if I miss a workout?
Not a problem. You have the option of either moving it to somewhere later in the week, deleting it, or just missing it. The coach automatically recalculates your stress balance and rebuilds the load across the week.

Do I need pool access?
Pool is ideal, but stretch‑cord and open‑water replacements exist. 

How does Athletica use HRV?
Nightly HRV readings inform readiness; low HRV triggers a warning from your AI-coach, high HRV suggests positive adaptation to the training and good recovery.

Which devices sync?
Garmin, Wahoo, Concept 2 and various devices like Polar, Coros, Suunto and Apple Watch via Strava and Intervals.icu; manual file upload is possible too.

Is strength training included?
Yes—weekly S&C from the HYROX global library keeps you strong.

Can I export workouts to my bike computer?
Yes—one‑click auto-export to Garmin and Wahoo; enjoy group rides and personal live coaching on Velocity with us.

What distance is a sprint triathlon?
Standard sprint format is a 750 m swim, 20 km bike and 5 km run—your plan targets those proportions but adjusts session length to your fitness.

Does the plan include nutrition or fueling guidance?
Yes—our podcasts, blogs, and Athletica U education series provide deep dives into sprint‑tri nutrition.
