The Eight-Week Sprint Plan That Made the Runner Slower
A 17-year-old sprinter with a personal best of 12.1 s for 100 m starts an eight-week off-season programme for the district meet. His coach's plan is: every morning 3 × 400 m at about 90% effort, then 200 sit-ups and 100 push-ups; every evening a 5 km run; no rest day; a 100 m time trial every Saturday; and on Sundays the athlete also plays an hour of football with friends 'for fun'. After five weeks his 100 m time is 12.3 s, his resting heart rate has risen from 58 to 70 beats/min, he wakes with a sore throat and has lost his appetite, and he reports a sharp pain along the inner edge of the shin during the 400 m repetitions. The coach's response is to add a second time trial each week to 'toughen him up'.
1. Which training principles has the plan broken, and which evidence in the scenario signals overtraining rather than normal fatigue?

Principles broken
- Recovery/rest. There is no rest day: two sessions daily, seven days a week. Adaptation happens during recovery, not during the work itself.
- Progressive overload with progression control. The load is high from day one and never cycled; volume and intensity are both maximal simultaneously, which is the classic route to overtraining.
- Specificity. A 100 m sprinter needs acceleration, maximum velocity and speed endurance. Daily 400 m repetitions and 5 km runs train a different quality and add fatigue without improving the 100 m.
- Variation/periodisation. The same week is repeated, with no unloading week and no phase structure across eight weeks.
- Individualisation and recovery monitoring. No sleep, heart-rate or wellness data are used to adjust the plan.
Signs of overtraining, not normal fatigue
- Performance falls despite increased training (12.1 s to 12.3 s) - the defining sign.
- Resting heart rate up 12 beats/min (58 to 70).
- Sleep and appetite disturbance, sore throat (immune suppression), persistent fatigue, and the recurring sharp shin pain.
Normal fatigue resolves within 24–48 hours and performance returns or improves; here every marker is moving the wrong way over five weeks, so the diagnosis is non-functional overreaching heading into overtraining.
2. Redesign one week of the programme using hard-easy days, and justify each session relative to the demands of the 100 m.

One-week microcycle
- Monday - Speed: warm-up, 3 × 30 m block starts, 3 × 60 m at maximum with 4–5 minutes' full recovery between runs, cool-down. Justification: maximum-velocity work needs full recovery; quality falls if fatigue accumulates.
- Tuesday - Tempo/recovery: 6 × 100 m at 65–70% with 45–60 s rest, plus mobility. Low intensity flushes metabolites without adding fatigue.
- Wednesday - Strength/power: medicine-ball throws, jumps, and a basic weight session (squat, hinge, pull) at moderate volume, plus core work. Justification: sprint performance depends on force production; this replaces 200 sit-ups daily with purposeful work.
- Thursday - Speed endurance: 2 × 150 m at 90% with 6–8 minutes' rest. Specific to the 100 m's final phase, without the volume of 3 × 400 m.
- Friday - Light technique + rest: starts, baton or drill work at low intensity, mobility.
- Saturday - Test or full rest: a 100 m time trial only every third or fourth week; otherwise a light session.
- Sunday - Complete rest.
Load logic: hard days are always followed by an easy or rest day; weekly high-intensity volume is stable rather than increasing every week; every fourth week is unloaded by about 40%. Football should be stopped during this phase because it is uncontrolled high-impact loading that cannot be monitored.
3. How would you manage the shin pain, and what is your judgement on the Saturday time trial and the coach's added second trial?

The shin pain
- Sharp pain along the inner border of the shin during repeated 400 m work on hard ground suggests medial tibial stress syndrome (shin splints) and, if it progresses, a stress fracture. The repetitive 400 m volume and the evening 5 km runs are the cause, not bad luck.
- Immediate action: stop the running that reproduces sharp pain; substitute non-impact conditioning (cycling, swimming, pool running) to keep fitness.
- Check footwear (worn or unsupportive shoes), running surface (concrete versus grass or synthetic), and ankle and hip strength; ice after activity.
- Red flags requiring medical referral: pain at rest, night pain, or point tenderness on a small area of bone - any of these means imaging before returning to impact, because running through a stress fracture can cause a complete fracture and months out.
The time trial judgement
- A 100 m time trial is a maximal test, so it is itself a high-intensity training session. Weekly trials add load and psychological pressure, and a trial every week is too frequent for reliable change anyway.
- The coach's second trial is the wrong direction: when performance has dropped and resting heart rate is elevated, more maximal efforts deepen the fatigue and confirm nothing. The correct decision is to test every 3–4 weeks, in a standardised warm-up and time of day, and to use training data in between.
- Over the next 1–2 weeks the priority is active recovery: reduced volume, sleep, adequate carbohydrate and protein, and monitoring resting heart rate each morning until it returns towards 58 beats/min.
