Verification Methodology

tlas World Records evaluated the achievement through activity-record reconciliation, GPS trace examination, geographic route reconstruction, documentary corroboration, and the applicant's signed-off written declaration.

Activity reconciliation: The adjudication team identified 757 GPS-backed cycling activities corresponding to the ChemoRiders journey. The original activity naming convention was compared against the applicant's description of the project, with minor naming variations reviewed separately.

Distance assessment: The accepted measurement uses the recorded cycling distances associated with the qualifying GPS-backed activities, supported by independent coordinate-based screening. The assessment identified GPS recording discontinuities and distinguished reported activity distance from artificial straight-line distances that could result from connecting separated coordinate points.

The review did not rely on adding arbitrary straight-line connections between disconnected GPS traces.

Excluded activities: Seven manually entered cycling activities, totaling approximately 261 miles, were excluded because corresponding GPS coordinate records were unavailable.

Repositioning: Six major transfers by air, bus, and rail were disclosed by the applicant and considered against geographic gaps between cycling activities. Noncycling repositioning distance was excluded from the record measurement. The applicant further declared that occasional local motorized travel was excluded from the Strava cycling measurement to the best of his knowledge.

Artwork development and eligibility: The adjudication recognizes that a GPS artwork may evolve during a documented journey and may incorporate earlier verifiable routes into a subsequently developed design, subject to the accepted routes forming an integral part of the completed artwork.

The applicant disclosed that the HELP! concept developed during the journey and became a publicly committed artistic objective in July 2025. Atlas evaluated the resulting artwork as a multi-stage geographic composition rather than as an uninterrupted bicycle ride.

Technical limitations: GPS records may contain signal interruptions, recording irregularities, and device-dependent distance variations. The review relied on activity records, geographic consistency checks, original GPS track availability, applicant disclosures, and supporting documentation. It does not represent that every original satellite measurement or subsequent platform adjustment was independently authenticated.
