Update personal best 4 minutes or more in half a year

Kokusai Landren's website introduces profiles of track and field athletes around the world.
According to it, Brigitte Cosgay, who marked the world record this time, was 25 years old from Kenya, born February 20, 1994.
The first marathon was held in Portugal in November 2015, four years ago, and this time was 2 hours 47 minutes 59 seconds.
After that, Kosgay shortens the record year after year.
Last year's Chicago Marathon won 2 hours 18 minutes 35 seconds. In addition, I won the London Marathon in April with a personal best of 2 hours 18 minutes 20 seconds.
In just half a year, Kosgay updated his personal best for more than 4 minutes. This time, he set a new world record of 2 hours 14 minutes 4 seconds.

Global high speed course

The Chicago Marathon is a mixed race marathon that began in 1977. Since the course is generally flat and easy to record, the world's top runners will participate.

In 2001, Kenya's Catherine Nudeleva won the world's highest record (2 hours 19 minutes 46 seconds) held by Japan's Naoko Takahashi at 2 hours 18 minutes 47 seconds.
The following year, Paula Radcliffe from England marked 2 hours, 17 minutes, and 18 seconds, setting a new record for Nudeleva.
(Radcliffe set the world record by marking 2 hours 15 minutes 25 seconds at the London Marathon in 2003)

Japanese players also have a good record at the Chicago Marathon.
In 1986, Toshihiko Seko won the second place in Japan in 1986 with 2 hours, 8 minutes, and 27 seconds. In 2002, Toshiari Takaoka was third in 2 hours, 6 minutes and 16 seconds, the highest in Japan at that time.
Last year, Jie Osako set a new record for Japan in 2 hours, 5 minutes and 50 seconds.
In 2002, Yoko Shibui was in second place in 2002, 2nd time in Japan's history, 2 hours, 21 minutes and 22 seconds.

About 5km / 16min pace

This is the Chicago Marathon.
The temperature at the start is around 5 degrees.
Cosgay struck the pitch lightly to follow the two men's pacemakers.
The first 5 km is 15 minutes 28 seconds.
After that, chop the pitch in about 5 km 16 minutes.

“I knew that this course was good last year. I had a little wind but there was no problem. The roadside encouragement became energy.” (Cosgay)

The pace of Kosgay is as follows (from the Chicago Marathon official record):
▽ 5km 15 minutes 28 seconds (5km: 15 minutes 28 seconds)
▽ 10 kilometers 31 minutes 28 seconds (5 kilometers: 16 minutes 00 seconds)
▽ 15km 47 minutes 26 seconds (5 kilometers: 15 minutes 58 seconds)
▽ 20km 1 hour 03 minutes 27 seconds (5 kilometers: 16 minutes 01 seconds)
▽ Intermediate point 1 hour 06 minutes 59 seconds ▽ 25 kilometers 1 hour 19 minutes 33 seconds (5 kilometers: 16 minutes 08 seconds)
▽ 30 km 1 hour 35 minutes 18 seconds (5 km: 15 minutes 45 seconds)
▽ 35km 1 hour 51 minutes 14 seconds (5 kilometers: 15 minutes 57 seconds)
▽ 40km 2 hours 07 minutes 11 seconds (5 kilometers: 15 minutes 58 seconds)
▽ Finish time 2 hours 14 minutes 04 seconds (world record)

The passing time at the midpoint is 1 hour 6 minutes 59 seconds.
Simply double that time, and the expected finish time is 2 hours 14 minutes. As expectations for the new world record increased, it was noted that the second half could run without disturbing the pace.

However, 5 kilometers from 20 kilometers to 25 kilometers slows down slightly at 16 minutes and 8 seconds. Even so, the next 5 km pace increased to 15 minutes 45 seconds, and then kept the 15 minute range.
Kosgay, who ran through the last straight line and pushed both hands high at the finish, won the world record of 2 hours 14 minutes 4 seconds. It was a phenomenal time to update Radcliffe's record for 1 minute and 21 seconds for the first time in 16 years.

As a TV broadcast guest, Radcliffe saw the moment when his record was changed locally, “I knew that the record would someday be broken. There was a chance to update the record by watching Kosgay's run at the midpoint. I knew. ”

The day before, the boy's Kipchoge, who was supported by 41 pacemakers, ran 42.195 km in 1 hour 59 minutes 40 seconds and had just achieved “the first 2-hour cut of humanity”.

The International Land Federation said, “Cosgay achieved the record within 24 hours after Kipchoge played“ the first two-hour cut of mankind ”, but the record was achieved in an official race, unlike Kipchoge. Praised.

As for Cosgay, this Chicago was the 11th full marathon.
Among them, he won seven times, and in 2016 and 2017 he won two consecutive wins in the Honolulu Marathon in Hawaii. It can be seen that it is not only amazing speed but also resistant to heat.
Next year's Tokyo Olympics are expected to race in the hot weather.
The representative of the Tokyo Olympics in Kenya has not been announced yet, but if Kosgay participates, there will no doubt be a Japanese rival as a female gold medal candidate.
