Nakuru Teacher to Attempt 45-Hour Maths Guinness World Record
A mathematics teacher from Nakuru will attempt to set a new Guinness World Record by teaching a continuous mathematics lesson for 45 hours at Menengai High School starting Friday, 30 January.
Fenwick Malobah aims to surpass the current benchmark for the longest individual mathematics lesson under Guinness World Records guidelines. His session will be open to the public, allowing students, parents, teachers and community members to attend throughout the attempt. Malobah said the challenge is intended to show that mathematics can be learned through sustained effort and consistent practice
The existing verified record stands at 31 hours, 42 minutes and 54 seconds, set in April 2025 by Nigerian student Sanusi Kazeem at the University of Ilorin. In November 2025, Emmanuel Onyegu, a graduate student at Utah State University, completed a 40-hour mathematics lesson, though that attempt is still under review. If confirmed, Malobah’s effort would exceed both records.
Kenya has previously held Guinness World Records linked to education. In February 2024, Rose Tata Wekesa of St Austin’s Academy set the record for the longest science lesson after teaching chemistry, physics and biology for more than 62 hours at Multimedia University. Her achievement was officially recognised by Guinness World Records.
The country has also produced several endurance-related records across different fields. These include Truphena Muthoni’s 72-hour tree-hugging challenge in Nyeri and Chef Maliha Mohammed’s 90-hour home kitchen cooking marathon. Kenya is also known for non-endurance milestones, such as Kimani Ng’ang’a Maruge, who enrolled in primary school at the age of 84 and later addressed the United Nations on access to education.
Ahead of recent record attempts, the Ministry of Health issued new guidelines in January 2026 requiring participants to undergo medical assessments before undertaking physically demanding Guinness World Record challenges. The ministry cited risks such as dehydration, extreme fatigue and organ strain. Recommended checks include blood pressure, blood sugar, haemoglobin levels and heart rhythm monitoring.
Guinness World Records requires strict compliance during record attempts. Participants are allowed only limited, scheduled breaks, and the entire session must be documented through continuous video recording. Independent witnesses must be present to verify adherence to the rules.
