Wil Chung (ambassador review) ↗

Original explicit “Rating: A-” for the 2018 London South experience. The article describes a five-mile Half loop plus another five miles for Full; the author’s chosen total, exact day, finish time and full obstacle performance are unstated. It was posted/reposted in April 2023; that publication is not the raced year. Historical Holmbush attribution is supported by the dated charity body and Horsham postcode, while its conflicting template address/distance fields are excluded. The author’s current Tough Mudder/361°/Enertor ambassador roles, discount promotion and unknown entry compensation are disclosed. No numerical thresholds are supplied, and A− is not converted to stars. Full original written review, grade and five exposed post images read. The map labels London South 2018; the featured-image URL names 2019 and does not prove a 2018 raced edition. Embedded video remains unwatched.

Source checked 2026-10-26. The original grade is preserved without conversion to stars or a Moku editorial score.

  • Tough Mudder London South 2022 ↗

    Wil Chung · 2022

    Chung enjoyed runnable woodland trails, an undulating route and spectator access from the central hub. He describes the new Slidin Dirty obstacle and running Infinity and a Sunday 10 km wave.

    Author currently discloses Tough Mudder and footwear ambassador roles. Historical 2022 account, posted in 2023. Descriptions of 5 km and 15 km obstacle options do not establish separate finishes or current layouts.

  • Tough Mudder London South — 2018 author grade A− ↗

    Wil Chung · 2018

    Chung gives the varied woodland-and-field course an A−. He values its cloverleaf spectator access, lively village and the return of Walk the Plank, while finding sections of the Full route run-heavy. He recalls a brief panic while waiting to surface after his first jump.

  • The dated British Obstacle Sports event listing verifies the edition; organizer course changes and session details remain subject to confirmation.
  • The original dated 2018 charity entry names Holmbush Estate in its body and Horsham/RH12 4SE in its address. Its isolated Culden Faw address label and generic 12-mile description conflict with those fields and the Half title, so they are not imported as venue/course facts. The author’s 2018 A− remains a historical London South course assessment, not the current 5/15 km layout or a confirmed raced day.
