5K time trial — skip, 23:53 already banked benchmark

Kept for completeness only. A time trial nine days after a race, on the first football week, buys nothing.

Time~40m
Distance7.5 km
DifficultyHard
Target: skip — the 2026-08-27 race cleared this bar; next test is the week-8 10K
OPTIONAL as of 2026-08-27. The Fossvogshlaup 5K on 27 August came in at 23:53 chip (4:46/km, avg HR 171, max 182), which clears this week's 24:30 bar two weeks early — so a second maximal 5K here buys a number you already have and costs a hard session. Run it only if you want a controlled comparison on a known course; otherwise take the session below and keep the race as the week-5 result.
Route: Run quality sessions on the FLATTEST route you have. Your routes now average ~14 m of climb per km — nearly three times your historical average — and goal pace on that terrain is a different, much harder session than the one written.

Calibrated by your 5K best effort (23:55 on 08-27, measured by Strava): threshold 5:03–5:15 · 1K reps 4:40–4:50 · 400s 4:22–4:35 /km — trust these over the printed bands.

2Same course every benchmark, as flat as you can find — ideally a track or a measured 5 km. GPS over-reads your distance by ~2%, so a watch-measured 5 km is really ~4.9 km; repeating one known course is what makes these times comparable to each other and to the goal.

Work

35 km time trial — even splits, no fast first km

This week's quality slot is already done (w5_q_tempo_sandwich on 2026-09-10) — marking this one replaces it.
