Kenyan’s Shadrack Kenduiywo breaks the nine year old world record for the Double 15k

The sport of Double Racing was created by Bob Anderson in October 2010. The sport, governed by the Double Road Race Federation (DRRF) is a two leg race with an established break between the legs.  

The featured event is the Double 15k.  The first leg is 10k. The second leg is 5k  The second leg starts one hour and 45 minutes after the start of first leg.  Times from the two legs are added together for scoring.  You must complete both legs to get an official time.  

Over 120 Double 15k races have been held around the world.  On May 10, 2015 Julius Koskei from Kenya broke his own world record clocking 43:11 in Pacific Grove California USA.  He clocked 29:11 for his 10k leg and 14:00 for his 5k leg.  

That record held for nine years and a few months.  On September 14, 2024 that record was not only broken but it was smashed at the fourth annual KATA (Kenyan Athletics Training Academy in Thika Kenya).  

24-year-old Shadrack Kenduiywo clocked 42:42 taking 29 seconds off the record.  He attacked the record right from the start clocking 28:33 for the 10k leg.  

He told us after the race, "This was my first double race and I was happy.  It was not my best time this year.  I had ran 28:18 this year in march in kapsabet betika and I was happy for this start."  

He told us he was in top form snd that he lead from the second kilometer.  Here was his splits: 2:52, 2:50, 2:57, 2:59, 2:57, 2:47, 2:41, 2:45, 2:55 and 2:50. 

We asked him what he did during the break. "During the break," he said "i just relax, drink water ate some fruits and then did a warm up of 20 minutes before the second leg."

His splits for the second leg were 2:47, 2:48, 2:51, 2:47, and 2:44.

After clocking the best time ever he said, "Yes if the weather could have cooler, i could have ran faster."  It was about 21c (71 F) at the start.  

We wanted to know a little more about Shadrack and he wrote, "In the half marathon, I have a personal best of 61:24 this year Italy padova, 25 km Berlin 1h15, 8km    23:43 and 5km 13:55 in Udeni."

The new world record holder says, "i hope to ran faster than this next time.  I will train next time focusing for it."

Shadrack was followed by Martin mumo who clocked 43:18 which is the third best time ever.  Only Shadrack and Julius Koskei have run faster.

KATA's Zachary kirika finished in third place clocking 43:37 which is the fourth best time ever.  very impressive considering the heat and he was unwell. 

Alice koigi took the crown in the women's race in a time of 49:30. She was followed by Monica wanjiku who posted 51:30 and Susan njuu stopped the clock at 53:07 which was good enough for third place.

In addition to the Double race, over 100 kids ran the Bob Anderson's Kids Mile.  12-year-old Benjamin ndaro clocked 4:54 with John Mwangi close behind clocking 4:59.  There was also a 5k for kids and 16-year-old Denis chege won in 17:48.
