Six Weeks to the Assessment
Recruit Tan is six weeks from the selection fitness assessment. Current bests: 2.4 km run in 13:20, 18 push-ups, 32 sit-ups. The pass standard is 12:30, 25 push-ups and 35 sit-ups, all tested in the same session with 5 minutes between items. He trains around a duty day that starts at 06:00 and ends at 18:00, and he averages 6 hours of sleep. Eight months ago he had medial shin pain that kept him out for five weeks; he says it settled with rest and has not returned. He currently runs 18 km a week, all of it at the same steady pace, and does no structured strength work. He wants to add a daily 5 km run and cut carbohydrates to lose 3 kg before the assessment because 'lighter is faster'. He has failed this assessment once before and is anxious about it.
1. Is the 2.4 km target realistic in six weeks? Quantify the demand and assess his proposed changes.
Read the worked answer
Convert to pace, because seconds per kilometre is what training actually changes.
- Current: 13:20 ÷ 2.4 = 5:33 per km
- Target: 12:30 ÷ 2.4 = 5:12 per km
- Required gain: 21 s per km, 50 s total, about 8 s per week.
For an untrained runner with an 18 km base, 8 s/km per week is achievable, and most of it typically arrives in the first three to four weeks from pacing and consistent volume. The push-up jump of 18 to 25 is a 39 per cent gain but achievable with three short strength sessions a week; sit-ups from 32 to 35 is small.
His own plan is the risk, not the target. Adding a daily 5 km takes him from 18 to 35 km a week - a 94 per cent jump - in a man with a shin-pain history: that is the classic progression that produces medial tibial stress injury. All his running is at one steady pace, so he is training endurance and none of the speed he is actually short of. Cutting carbohydrate while sleeping six hours reduces recovery and raises injury and illness risk, and losing 3 kg in six weeks is only defensible through a modest deficit, not through under-fuelling quality sessions.
2. Set out a weekly training structure with safeguards, and explain why each element is there.

Weekly structure (about 22–24 km, rising no more than 10 per cent per week)
- Mon: strength - push-ups in sets to 40 total, pull-ups, core, calf raises, single-leg work. Builds the push-up standard and tendon capacity the running depends on.
- Tue: intervals - 6 × 400 m at target 2.4 km pace with 90 s recovery. This is the only session that directly trains 5:12/km.
- Wed: easy 4 km plus a short strength circuit.
- Thu: tempo 3 km or 6 hill repeats - strength endurance without the pounding of a long fast run.
- Fri: strength and mobility only, no running.
- Sat: long easy run 6–8 km, conversational.
- Sun: full rest.
Safeguards: at least one full rest day; sleep raised towards 7 hours; carbohydrate kept around quality sessions rather than cut globally; a pool or bike substitute ready for any shin symptom; the last 10 days taper volume while keeping intensity. In week 5, rehearse the test order - push-ups, sit-ups, then the run - so his pacing is not derailed by fatigue he has never practised.
3. At the start of week 3 he reports shin soreness. What is your decision rule, and how do you avoid over-reacting or under-reacting?

Use thresholds agreed before the symptom appears, so the decision is not made on mood or on how badly he wants it.
Stop running and substitute non-impact work for 5–7 days if any of these: pain present in the morning before training; pinpoint pain over a 2 cm area on the tibial border; pain that increases as the run goes on; pain above 3 out of 10; pain on hopping.
Continue with modified load if: the ache is diffuse, warms up and settles within the session, and is gone by the next morning. In that case, cut weekly volume by 30 per cent, keep the interval session on the bike or in the pool, and reassess in seven days.
Escalate to the medic if pain persists beyond seven days of reduced load, if he cannot hop, or if the pain is in one spot and worse at night.
Two disciplines make this work. He records a daily pain score and morning status, so 'it feels okay' becomes an observation rather than a hope. And the rule is applied by me, not negotiated by him - an anxious candidate who has failed once will always say he is fine, which is precisely why the threshold cannot be his to set in the moment.
