MixedThey find the Trainer v3 polarizing: energy return is mid, but the dense foam makes it a good steady-pace long run workhorse that seems to last forever.

Blog · Believe in the Run – Meaghan Murray, Thomas Neuberger · summarized
PositiveA solid update to one of a favorite daily trainers, designed for the marathoner: comfort for tired legs plus a responsive, bouncy ride for weekend long runs. Fans of v1 and v2 should be happy.
Blog · Runner’s World UK – Ali Ball · summarized
PositiveA firm yet cushioned ride, subtle rocker and secure lockdown that had her looking forward to every run, which is rare for a heavy tester. Her main contention is the 'eye-watering' £230 price.

MixedB to A-: One tester's current choice for long runs and workouts, and another's go-to for tired legs and time on feet. One tester likes the ride, but toenail pain limited her to ≤8-mile runs.

PositiveA runner enjoys the SC Trainer v3 for weekly long runs and feels the energy return, though the v2 felt more cushioned for long distances.
YouTube · Michael Ottesen · Sep 23, 2024 · summarized
PositiveJust over 100 miles of easy runs, long runs and workouts, including sub-5:00 mile reps. Soft, bouncy and very well cushioned, a favorite for long runs and fine up to tempo pace but not much faster. The upper locks the foot down comfortably and breathes well. The outsole is the weak spot, with poor traction and quick wear, and the shoe feels a bit heavy and clunky.

PositiveAfter a 21-mile run, a runner says the SC Trainer v3 performed exceptionally and felt very responsive.
