There are a lot of people at the start. They are cheered on by thousands of people on the streets.

It depends on where you are in the world. There are a million runners at the start line. The world's population has never run a marathon.

A joke in the running community is to say "never again" and then sign up for another race. The Abbott World Marathon Majors include Berlin, Boston, Chicago, London, New York City and Tokyo. 103 countries are represented by the 8,066 six-star finish after the Chicago Marathon.

The New York City Marathon will be the final major of the year and 73 runners will be aiming to join the list of six-star finishes. These athletes are not known. elite runners aren't the only ones

Here are five people who have done it and one who is hoping to get a star in New York on Sunday.

Ron Romano, age 61

Ron is wearing Abbott World Marathon Majors gear. He has a hat on his head. His medal rack is behind him.

He knows that running is his passion. There is a lot of energy in Romano. Ron runs NYC and talks to runners from all walks of life on his social media. He enjoys talking about running.

The world majors were tackled by Romano at 58. He was not trying to be competitive when he ran the NYC marathon. He started running in his 30's. He hired a coach and began to work on his training after realizing that long distances suited him.

"You gotta stay in the fight" is the motto of the man. She has been through a lot in her life, but she keeps going. He is motivated by this. All six marathon majors were run by Romano in one calendar year at an average time of 3 hours and 15 minutes. He was one of only 19 people to do it that year, and only 22 people have ever done it in a single year.

On Sunday, he will run New York with a goal of finishing under 3 hours.

Edna Kiplagat, age 42

"Alright, let's go mom!" As her husband drives alongside her with her children in the back, she hears what she wants to hear.

They're supporting her during her run. He started playing soccer at a young age and then switched to track. In middle school, she was already running faster than everyone else. At a young age, she began to qualify for international races.

"Running doesn't come without lots of training and working hard, and the best athletes find happiness, joy and excitement from their sport," she said. The person feels like they are running.

Since winning her first major marathon in New York City in 2010, she has won two of the other majors. She won a gold medal in the marathon at the world athletics championships and will return to New York to run on Sunday.

Her husband is also her coach. They plan for months so she is ready for the race.

"Eating a healthy diet, staying hydrated, getting enough sleep and seeing the big picture are all important components to being marathon ready," she said.

Manuela Schär, age 37

At the age of 8, an accident forced Schr to look for a new sport. When she was 11 years old, she started racing in a wheelchair.

Schr is a part of Switzerland's history in wheelchair racing. In the last two years, she has won seven marathon majors in a row. She won the gold medal for the 400 and 800 meters in the Paralympics.

Schr appreciates all of the challenges that different majors throw at her, and she loves travelling and the marathon distance. She says you have to be good at both the flats and the downhill sections of the course to be the total athlete.

In 1975, the Boston Marathon became the first major marathon to include a wheelchair division.

The Abbott World Marathon Majors include wheelchair racing. The ability to be a role model is one of the benefits of this. The future of the sport is supported by including wheelchair racing.

Schr won the NYC Marathon three times in a row in the last two years.

The marathon turned into six for Rene and his family. Rene has been running for 50 years. He was the first person to run a marathon. The New York City Marathon was canceled in 2012 due to Hurricane Sandy.

They were able to run in New York. They joke that they don't know why they sign up every year to wake up at 6 a.m. and wait three hours in the cold for the race to start.

Rene says running the marathon isn't a good way to train for a marathon. I like the distance because it's a little too far for me.

They like to motivate each other. They can't run as much as they want because they don't live close to each other. They made it work.

Dirk says Gijs and he felt we needed to catch up after he found out his dad ran more kilometers than him.

They decided to run all the races after hearing about the marathon majors. It was difficult to get all three of them into a race. Rene usually qualified into his age group based on his times, even though they entered the lottery or used a tour operator.

They finished their sixth marathon in Boston in April to get their medals. The van Hunsels said the cheers they got made them feel like celebrities.

Ciaran Diviney, age 50

Ciaran Diviney decided to start running again after 20 years. He ran the Berlin Marathon with a group of friends. It took him 3:09 to complete it. He said he caught the running bug.

When he started training, it was more of a solo mission, but he began to run into people on his runs. He joined their local athletics running club after meeting with others who were also training for the Dublin Marathon.

He changed his life. He met the love of his life at the running club and they now have a family. A marathon PR of 2:35:30 is achieved by Diviney self-trains.

The more he learned about marathon majors, the more he wanted to finish them. There is a prestige about them. I realized that this was something I could complete and I was looking forward to it.

He ran the Dublin Marathon last Saturday before flying to New York for his 15th marathon. He will get his sixth star finish medal if he completes NYC.

Jennifer Solomon has completed the six major marathons, then took it one step further: She ran a marathon on seven continents in seven days. Jannelle Cioffi

Jennifer Solomon, age 49

The smoker was smoking a pack of cigarettes a day. She says she smoked for fifteen years. She wanted to change to a healthier lifestyle when she was 40. When she gained weight, she started running.

She didn't consider herself to be an athlete. She didn't have a lot of time for herself, but she did have time to run.

Solomon ran the Manchester City Marathon in New Hampshire and the Boston Marathon for Boston Children's Hospital after starting with a 5K race.

Solomon says, "As a grown up, I feel like we have few things that we do that we can be proud of ourselves for." There was a rush of finishing in every training cycle and race. I really liked that feeling.

Solomon did not miss a marathon in the year 2019. She raised $60,000 for children's charities by running with charity bibs. She didn't mind that her kids would brag about her marathon accomplishments to their friends.

She thought to herself, "Don't stop until you're proud."

Solomon flew home after each race to see her children. She ran a marathon on seven continents in seven days after finishing all the world marathon majors.

I don't know how I pulled it all together, it was hard. I just planned for the week ahead so I wouldn't be scared off.
