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.
