Thomas Scheer completed 29 officially organized triathlon races with advertised distances of at least 113 kilometres within a single one-year period. His verified schedule included both half-distance and full-distance triathlons, producing a final total three races greater than his previously recognized benchmark of 26.
Transparent Adjudicator's Statement
Summary of Claim
Thomas Scheer submitted a claim seeking recognition for completing the greatest number of triathlon races of 113 kilometres or greater within a one-year period.
The original submission described the achievement primarily in terms of 113 km or 70.3-mile triathlons. During review, Atlas identified that two qualifying events—races 13 and 16—were full-distance 140.6-mile triathlons rather than half-distance 70.3-mile events.
Because both races exceeded the minimum distance represented by the underlying record category, Atlas refined the record definition to establish 113 km as the minimum qualifying distance, rather than requiring every race to be exactly 113 km.
The final record title was therefore established as:
Most Triathlon Races of 113 km or Greater Completed in One Year
Under this definition, officially organized half-distance and full-distance triathlons qualify, while shorter-distance triathlon formats do not.
Evidence Submitted
Atlas World Records reviewed a substantial body of documentation supporting the 29 claimed race completions. The submitted evidence included:
Race-by-race supporting evidence packets
Official and publicly available race results
Finisher documentation
Participant and bib records
Independent witness statements
Timekeeper statements
Photographic evidence
Race schedules and event information
An itemized record-attempt log
Public race and event documentation
Supporting social-media and online records
The principal submission contained documentation for the claimed events throughout the one-year period. Race 28, the Outlaw Holkham Half, was separately documented as having been completed on July 5, 2026, with a recorded finish time of 8:57:16.
Comparative and Cross-Archive Benchmark Review
Atlas World Records cross-referenced the publicly available records maintained by all major world record organizations for comparable achievements and established benchmarks.
The review confirmed that Thomas Scheer was already the recognized holder of the existing benchmark at 26 qualifying races completed within one year. His present submission therefore represents an attempt to improve upon his own previously recognized record.
Atlas also reviewed earlier published benchmarks for comparable achievements and found that the prior figure of 24 races had subsequently been surpassed by Scheer’s own recognized total of 26.
The present submission documents 29 qualifying triathlon races of 113 km or greater completed within the defined one-year period, exceeding Scheer’s own previous benchmark by three races.
Based on the comparative and cross-archive review, no higher publicly available benchmark was identified that would displace Scheer’s submitted total of 29.
Verification Methodology
Atlas World Records reviewed the submission on a race-by-race basis rather than relying solely upon the aggregate total presented by the claimant. For each event, adjudicators assessed, where available:
The identity of Thomas Scheer as the participant
The event name
The event date
The officially advertised race distance
Completion status
Recorded finishing time
Supporting witness or timekeeper documentation
Consistency between submitted documentation and event records
Whether the event occurred within the qualifying one-year period
Whether the event met or exceeded the 113 km minimum distance
Whether any submitted event was duplicated within the final count
Atlas also examined the chronology of the complete race schedule to confirm that all qualifying performances fell between July 12, 2025 and July 11, 2026.
Special review was undertaken for races 13 and 16 because each was a full-distance 140.6-mile triathlon rather than a 70.3-mile half-distance event. Atlas determined that both events satisfied the final record definition because each exceeded the established minimum qualifying distance of 113 km.
Documentation for race 28 was reviewed separately and confirmed as the Outlaw Holkham Half, an organized half-distance triathlon completed on July 5, 2026.
Adjudication Findings
Atlas World Records finds that the evidence supports 29 distinct qualifying triathlon completions by Thomas Scheer during the defined one-year period.
The majority of the submitted events were half-distance triathlons totaling approximately 113 km or 70.3 miles.
Two events, races 13 and 16, were full-distance triathlons totaling approximately 226 km or 140.6 miles. Atlas did not classify these races as 113 km events. Rather, they were accepted because the record definition establishes 113 km as a minimum qualifying distance, and both full-distance events exceeded that threshold.
The submitted documentation also establishes the completion of race 28, resolving the numerical sequence of the 29-race submission.
Atlas therefore finds that Scheer completed 29 qualifying triathlon races and exceeded his previously recognized benchmark of 26.
Conclusion
Following review of the submitted evidence, race documentation, chronology, event distances and comparative benchmarks, Atlas World Records verifies that Thomas Scheer completed 29 triathlon races of 113 kilometres or greater within one year, from July 12, 2025 through July 11, 2026.
Atlas World Records therefore recognizes Thomas Scheer as the holder of the record:
Most Triathlon Races of 113 km or Greater Completed in One YearVerified metric: 29 qualifying races.
The achievement represents an improvement of three races over Scheer’s previously recognized benchmark of 26.
