Kenyan mathematics teacher Fenwick Cyril Maloba of Menengai High School in Nakuru completed a 45-hour continuous mathematics lesson as part of a Guinness World Record attempt.
The teaching marathon began on June 26, 2026, under the theme “Mathematics Is Not A Monster.” The initiative aimed to encourage learners to embrace mathematics and to demonstrate endurance in teaching.
Maloba’s attempt sought to surpass the previous record of approximately 31 hours and 43 minutes, with the session conducted under Guinness World Records guidelines, including continuous monitoring by witnesses and rotating groups of students.
During the challenge, Cyril Maloba crossed the 24-hour mark before completing the full 45-hour lesson.
By Saturday, June 27, Maloba had already crossed the 24-hour mark, remaining on course to complete the marathon lesson at Menengai High School.
Speaking about the challenge, Cyril Maloba said his mission extends beyond breaking a world record.
“I’m taking on this 45-hour challenge to prove that ‘Maths is not a monster; it’s a marathon.’ If I can teach it for 45 hours straight, anyone can learn it for life. Let us put Nakuru and Kenya on the global map.”
Guinness World Record Cyril Maloba Set Out to Beat
Before Fenwick Cyril Maloba’s attempt, the Guinness World Record for the longest mathematics lesson was held by Sanusi Kazeem of Nigeria, who taught continuously for 31 hours, 42 minutes, and 54 seconds in Ilorin on April 12, 2025.
According to Guinness World Records, the record requires one teacher to conduct a mathematics lesson for a class of at least 10 students, with the duration measured in hours, minutes, and seconds.
The attempt must also meet strict verification requirements before it can be officially recognized.
Before Kazeem’s achievement, other mathematics teaching marathons had also been staged outside the Guinness World Records framework.
