British players preparing at the US Open are reporting their practice sessions have been affected after a marijuana smell drifted across outdoor training courts from a nearby park.

The odor has reached the practice zones where players fine-tune serves and movement between matches, prompting complaints from the British contingent. Katie Boulter confirmed she has encountered the smell, saying, "I’ve experienced it."

The immediate consequence is a distraction during critical preparation time. Practice windows at a Grand Slam are limited, and even short interruptions can force players to alter warm-ups, postpone drills, or accept noisier, less controlled conditions. For competitors who rely on tightly timed routines, an unavoidable external smell becomes more than an annoyance, it becomes a variable in match readiness.

The incident highlights the challenge of staging major tournaments in urban settings where public spaces border sporting facilities. When odours from adjoining parks or streets infiltrate training areas, organisers face a choice between accepting occasional disruption and putting measures in place to shield athletes from environmental disturbances.

Players and coaches will need to weigh whether to change practice times, move to alternative courts if available, or proceed and adapt despite the distraction. For those on the British team, reporting the problem publicly signals frustration and raises the possibility that others will notice the same issue.

The situation is likely to prompt internal discussion within camps at the tournament about how best to protect preparation. It may also bring renewed attention to how venues and local authorities manage recreational activities near elite sports facilities as the event continues.
