On 6 June 2026, Spanish endurance athlete Vicente Blanco Saunders completed the Spartan Race Ultra in Andorra while wearing a weighted vest with a verified minimum weight exceeding 10 kilograms. The attempt was conducted during an officially timed Spartan Race Ultra event and was documented through pre- and post-race weight verification, GPS tracking, official timing, witness statements, and supporting video evidence.
Transparent Adjudicator's Statement
Summary of Claim
Vicente Blanco Saunders submitted a claim to Atlas World Records for completing a Spartan Race Ultra while wearing a weighted vest with a minimum certified weight of 10 kilograms. The attempt was completed under standard Spartan Race Ultra conditions, with the athlete participating alongside other registered competitors, following official course rules, obstacle requirements, timing protocols, checkpoints, and cut-off standards.
The record was structured as an individual athlete achievement. Spartan Race Spain authorized contextual use of its name in connection with the certification, while the record itself is held solely by Vicente Blanco Saunders.
The athlete completed the course in an official time of 12 hours and 47 minutes.
Evidence Submitted
Atlas World Records reviewed a comprehensive evidence package, including but not limited to:
Pre-race scale validation video using a factory-marked reference weight
Pre-race video of Vicente Blanco Saunders weighing in without the vest
Pre-race video of Vicente Blanco Saunders weighing in while wearing the weighted vest
Post-race video of Vicente Blanco Saunders weighing in while still wearing the vest
Post-race video of Vicente Blanco Saunders weighing in after removing the vest
Video and photographic documentation of the weighted vest
Documentation of tamper-evident security seals applied to the vest
Official Spartan Race Ultra timing and results
GPS activity file for Vicente Blanco Saunders
GPS activity file for Samuel Durán, the principal on-course witness
Witness statement from Samuel Durán confirming continuous visual observation of the athlete during the race
Witness documentation from Ángel Sanz, CEO of Spartan Race Spain, supporting event verification and race-day confirmation
Additional witness documentation from start and finish verification witnesses
Supporting race-day video and photographic evidence
Official event documentation, including athlete guide and course-related materials
Supporting documentation submitted through the athlete’s evidence archive
Comparative and Cross-Archive Benchmark Review
Atlas World Records conducted a cross-archive review of publicly available record listings at all major world record organizations and did not identify a previously certified record for an individual completing a Spartan Race Ultra while wearing a weighted vest meeting a minimum 10 kg threshold.
Atlas acknowledges that anecdotal or informal claims may exist within the obstacle-course racing community regarding prior participation in Spartan events while wearing weighted vests. However, those claims were not found to have been formally certified as world records, nor were they publicly supported by a comparable evidence file containing pre- and post-race weight verification, official race timing, GPS course completion data, and independent witness testimony.
This certification therefore establishes the first formally documented and independently verified benchmark for this record category.
Verification Methodology
Atlas World Records evaluated the claim according to the following verification standards:
The athlete was required to complete a Spartan Race Ultra under standard race conditions.
The athlete was required to wear a weighted vest with a minimum verified weight of 10 kilograms.
The weighted vest had to remain worn throughout the duration of the race.
The athlete’s completion had to be supported by official race timing.
The athlete’s course completion had to be supported by GPS tracking.
The vest weight had to be confirmed through recorded pre- and post-race weigh-in procedures.
An on-course witness had to observe the athlete during the race and provide a signed statement confirming that the vest was not removed.
Additional witness documentation was required for the weigh-in and post-race verification process.
Atlas reviewed the submitted weigh-in videos to confirm the scale validation process, the athlete’s body weight without the vest, the athlete’s weight with the vest, and the resulting differential. The submitted evidence confirmed that the weighted vest met or exceeded the required 10 kg minimum threshold.
Atlas also reviewed the official race result, GPS activity records, witness statements, and supporting visual evidence to confirm that Vicente Blanco Saunders completed the Spartan Race Ultra while wearing the weighted vest.
Adjudication Findings
Atlas World Records finds that Vicente Blanco Saunders successfully completed the Spartan Race Ultra in Andorra on 6 June 2026 while continuously wearing a weighted vest meeting the minimum 10 kg requirement.
The official race timing confirmed completion of the event in 12 hours and 47 minutes. GPS evidence supported course completion, while the accompanying GPS activity from Samuel Durán supported the witness claim that he remained with Vicente throughout the race. The principal witness statement further confirmed that the vest was worn continuously and was not removed during the attempt.
The pre- and post-race weigh-in evidence confirmed that the vest met or exceeded the required minimum weight threshold. The use of tamper-evident seals provided an additional layer of integrity, although the primary verification structure rested on video-documented weight confirmation, official timing, GPS records, and independent witness testimony.
Based on the evidence submitted and reviewed, Atlas World Records finds the claim to be valid.
Conclusion
Atlas World Records hereby certifies Vicente Blanco Saunders as the first individual to complete a Spartan Race Ultra while wearing a weighted vest with a minimum verified weight of 10 kilograms.
This achievement establishes a new world record benchmark in obstacle-course endurance performance and is recognized as a formally documented, independently verified, and Atlas-certified world record.
