The sprint scene in Kenya is undergoing a quiet revolution led not by veterans, but by a new generation of raw, fearless talent.
Among the most electric names making waves is Dennis Mwai, a 19-year-old whose meteoric rise from barefoot races in school to rubbing shoulders with elite sprinters is the stuff of sporting folklore.
It was during the 2024 Kenya Secondary Schools Sports Association (KSSSA) national games in Machakos that Mwai’s life changed.
Then, a Form Four student, Mwai, turned heads with his blistering pace and was promptly scouted by the newly formed Omanyala Foundation, an initiative started by Africa’s fastest man, Ferdinand Omanyala.
“I was approached by a scout who told me that Omanyala was starting a foundation and that they wanted me to be part of it,” Mwai recalls.
“I was so excited because that was highly recognised, more so because this was Kenya's top sprinter.”
He, alongside Clinton Aluvi, shone at the 2024 National KSSSA games in Machakos, both being scouted to join the Omanyala Foundation.
Later that year, the boy who once idolised Omanyala met his hero in person at the Moi Stadium, Kasarani.
“We met Omanyala at the Kasarani Stadium, where he offered us some kits and he talked to us at length about our future in sprinting.”
“It was like a dream come true for me. Before I officially met him, I only used to hear about him and the achievements he has had on the track.”
“He had been my role model, and I wanted to achieve all he had been able to achieve on the track. People in my school used to call me Omanyala because of my sprinting capability,” he said. Mwai recalls being star-struck, having met Omanyala up close and personal.
“He was so big and muscular, and as for m,e I was short and tiny. I want to be like him one day.”
At the 2024 games in Machakos, Mwai produced a dominant display, claiming the 200m national title and placing fourth in the 100m.
However, he recalls that stepping up to the big stage came with its nerves.
“I ran well in the heats and semis, but when we got to the finals, I was a bit nervous.”
“In the fina,l I was set to go up against Daniel Wasike. He was the biggest threat to me in that race because his performance and stats throughout the competition and in the Regional games showed he was a tough competitor.”
Despite the anxiety, Mwai remained unbothered and decided to put his best to secure victory. “I gave myself morale and decided to push on, and eventually I won the race. It was such a great feeling.”
Born on September 24, 2005, at Pumwani Hospital in Nairobi, Mwai’s journey began far from tartan tracks and television lights.
An only child raised by his mother, Agnes Wangui, he moved between Nyeri and Mombasa in his primary years – attending Kiamurathe Primary and later Fahari Primary, where his love for running blossomed.
“While in primary school, our science teacher used to instruct us to take a lap around the field to be fresh for his lesson. Not many students used to like it, but for me, I loved doing it; running was fun.”
“During PE classes, I also used to love running around, specifically in the sprints – 400m and 200m,” Mwai recalled.
By Class Seven, Mwai had already won county titles in the 200m and 400m. But just as he was preparing for regionals, the COVID-19 pandemic halted everything.
“I got to represent my school in the county games while in class seven and won the 200m and 400m events. However, as we were preparing for the regionals, Covid came and that disrupted all sporting events,” Mwai noted.
In high school, Mwai joined Mukurweini Boys before transferring to St Augustine Gikondi Boys in Form Two. After joining high school, Mwai opted to drop the 400m and focus on the shorter sprints – 100m and 200m.
“In high school, I decided to drop the 400m because it was tiresome running all three events,” he said. Without a sprint coach, he had to chart his course.
“I did not have a coach while in school. In high school, the only coach available was only focused on football, leaving me to train myself.”
“I did not know the essentials or the basics of training for sprints. I used to do two repetitive sprints for the 100m and once for the 200m; that was my basic training. At the time, I thought that's all it took.”
Proper running shoes were also a major hurdle for him. “I did not have the proper running shoes. I used to run barefoot in my competitions up to the regionals, where we would be provided with proper running shoes. Sometimes I used to look at other kids and wonder why I didn’t have the proper running gear like them.”
“That, however, only fueled my desire to shine and claim more accolades,” he says. True to his ‘never say die attitude, Mwai would shine at the regional championships in the 200m, securing a maiden nationals appearance. However, his national debut did not go as planned, as he finished last, intimidated by bigger, older competitors.
“It was my first time on the national stage, so I was nervous. The other students were way bigger and taller than me. I was very short, but I gained a lot of experience from that.”
He, however, returned stronger in 2023, placing third in the 200m at the nationals and earning a spot at the East Africa Secondary Schools Games in Rwanda, where he helped Kenya’s 4x100m relay team clinch gold.
“The coaches motivated us and told us that the 4x100m team always came back home with gold, so our team should be no different. It was a great feeling winning gold on the regional stage.”
But it was 2024 that proved to be his breakout year. Now more confident and still self-trained, Mwai dominated the KSSSA national games in Machakos to earn another appearance at the regional extravaganza.
At the East African Games in Uganda, he struck gold again in the 200m and the 4x100m relay.
His performance caught the attention not only of the Omanyala Foundation but also Perpetual ‘Perps’ Mbutu, head coach at Utawala Sprints Club.
“Many promising athletes don’t make it past high school because they have no motivation to chase their dreams on the track. Actually, for me, it was the Omanyala Foundation and Coach Perpetual, who followed up after school.”
“After I completed my high school, Coach Perps took me in because the Omanyala Foundation was not yet functional.”
He recalls vividly how different training under a coach was.
“At first, training was very challenging. In high school, I did not know the basics of sprint training, so when Perps started training me. It was a huge hurdle for me.”
“After some training sessions, I would throw up, and the other athletes would laugh at me. But that did not stop me, I kept on pushing, and now I have surpassed some of those who used to laugh at me.”
Mwai’s senior debut came on March 1, 2025, at the Athletics Kenya (AK) Track and Field weekend meet in Thika. He clocked a stunning 10.2 seconds— a statement of intent on his senior debut. Mwai tied with Isaac Omurwa on time but finished second behind veteran Boniface Mweresa (10.1).
“I felt so good to finish second because not so many athletes start their senior careers and get on the podium. Before the finals, I only knew Omurwa. I had not heard of Mweresa, but as we were running in the final, I thought I had the lead only to look to my side and see he (Mweresa) was slightly ahead,” Mwai said.
He was soon invited to the World Relay trials in April, but nerves got the better of him. Mwai clocked 10.63 to finish a distant sixth with Meshack Babu (10.39), Moses Onyango (10.47) and Omurwa (10.49) claiming the podium.
“In that race, I learnt the importance of running my race. At the start line, I looked at the other athletes and told myself none of them would be able to beat me, but unfortunately, I ended up performing badly.”
Redemption came with an invitation to the Kip Keino Classic World Continental Tour gold level meet on May 31 at the Ulinzi Complex.
“Getting that invitation came as a shock to me. I was expecting the likes of Samuel Chege and Mike Mokamba to get the invitations, but I was so excited and I wanted to do my best and shine on such a big platform,” he said.
He, however, missed the podium places, finishing sixth in 20.91 with Liberia’s Joseph Fahnbulleh (20.40), South Africa’s Shaun Maswanganyi (20.47) and Switzerland’s William Reais (20.72) claiming the podium places.
“I was not pleased with the time I got. I was hoping for 20.24. The last 50m was a challenge for me, and I also did not go through the curve as expected. However, I take that as a learning experience.”
Mwai’s most recent outing came at the Nyeri County Championships, where he cruised to wins in both the 100m (10.5) and 200m (21.3).
His main aim for taking part in the Nyeri championship was to motivate other sprinters in the region, as he had been motivated.
“There are not many sprinters in Nyeri, so the competition was not fierce. There are no coaches to train sprinters, and those who are there only focus on the long distances. The main reason I took part in those championships was to give back and try to uplift young sprinters and give them a helping hand,” he noted.
Off the track, Mwai is chasing another dream: a scholarship to South Plains College in the U.S. “I got a scholarship from South Plains College in the USA, but I am waiting till August for the confirmation.”
For now, he trains six days a week, focusing on speed endurance runs ranging from 150m to 350m.
“I sometimes run between 350m, 250m or 150m based on the daily programmes I get from the coach, with my rest day being Wednesday. Currently, I do not do gym work, but I will be starting from July.”
Confident and quietly determined, Mwai has his eyes set on bold targets – the 20.16 entry standard for the Tokyo World Championships.
“Right now, I am working hard to meet the entry mark for Tokyo. I have a personal best of 20.7, and I am confident I can trim that to meet the time for Tokyo.”
Over the 100m, Mwai is optimistic he is Kenya’s and the continent, next big name.
“In the next two years, I am very confident I will be running sub-10-second races.”
