Ten consecutive days of World Championship track and field begin tomorrow afternoon in Doha, Qatar. Here is the best thing to watch on each day from Sep. 27 to Oct. 6.

Day 1 - September 27

Women’s Marathon - 11:59 PM Doha Time

Just how miserable a midnight marathon run in dreadful heat and humidity is will be answered quickly in Doha as the women race at 11:59 PM on the first day. The best-case scenario is this not turning into a debacle of mass DNFs.

Day 2 - September 28

Men’s 100m - 10:15 PM Doha Time

Christian Coleman did not race between USAs and Worlds due to his whereabouts case that was ultimately dropped, but he remains the huge favorite for 100m gold. Coleman’s calling card is his electric start, and I’m curious if that aspect will still be sharp two months since his last contest. His primary foe — if he’s 100 percent — will be 37-year-old defending champion Justin Gatlin.

Day 3 - September 29

Women’s 100m - 11:20 PM Doha Time

Aside from the women’s 4x100m, this race will be the highlight of the meet for the Jamaicans as co-world leaders Elaine Thompson and Shelly-Ann Fraser-Pryce look to sweep the top two podium spots. They’re the only two women in the field to run 10.7 this year, but Great Britain’s Dina Asher-Smith is a contender after beating Fraser-Pryce earlier this month.

Day 4 - September 30

Men’s 400m Hurdles - 10:40 PM Doha Time

The first world record of the championships could fall on the fourth day as three sub-47 second men — Karsten Warholm, Rai Benjamin, and Abderrahman Samba — will line up together for the first time ever. In this deep of a race, a lowering of Kevin Young’s 46.78 world record is likely to be a byproduct of winning gold. Warholm and Benjamin both went 46.9 last time out, but Samba is a wildcard as the hometown favorite hasn’t raced since July.

Day 5 - October 1

Men’s 200m - 10:40 PM Doha Time

Noah Lyles will win his first gold medal on Oct. 1, 2019. I’m confident of at least that much for a man who has (mostly) looked untouchable over 200m throughout his professional career. Everyone will be watching to see how the boisterous sprinter celebrates, but save a glance for the clock: Michael Johnson’s 19.32 American record isn’t out of reach for a man who ran 19.50 three months ago. 

Day 6 - October 2

Men’s 110m Hurdles - 11:00 PM Doha Time

Jamaican Omar McLeod will go for his third consecutive global championship gold in an event that is one of the most unpredictable of the meet. Grant Holloway’s 12.98 world lead feels like it’s from another lifetime — it was nearly four months ago at NCAAs, after all —and you can’t call him the favorite after a runner-up finish at USAs. U.S. champion Daniel Roberts and Diamond League winner Orlando Ortega have had their moments, too, but no one is ahead of the pack. 

Day 7 - October 3

Women’s 400m - 11:50 PM Doha Time

There hasn’t been a Shaunae Miller-Uibo vs Salwa Eid Naser 400m battle in over a year, but the last time they met their times were 48.97 and 49.08, respectively. More will be expected this time with gold on the line. Miller-Uibo has been the most dominant track and field athlete in the world during her undefeated run during the last two years. In the wake of a 21.74 200m earlier this month, she could pop off something really special over 400m in Doha. Naser is the only woman who can push her all the way to the line.

Day 8 - October 4

Women’s 400m Hurdles - 9:30 PM Doha Time

A world record has already been broken this season, but two world records in one season is a legitimate possibility after Sydney McLaughlin unseated Dalilah Muhammad in the Zurich Diamond League final. McLaughlin hasn’t come close to Muhammad’s 52.20, but a consistent season could yield a big drop in time when fully peaked.

Day 9 - October 5

Men’s 4x100m - 10:15 PM Doha Time

Most casual track fans are familiar with the calamity that has been the U.S. men’s 4x100 relay over the last decade and a half. Between dropped sticks, running out of the zone, and Usain Bolt, the Americans haven’t won global gold in this race since 2007. With no Bolt, that should change in 2019 with the U.S. trotting out another star-studded lineup with Christian Coleman and Noah Lyles. The key word there is "should."

Day 10 - October 6

Men’s 1500m - 7:40 PM Doha Time

The men’s 1500m is the highlight of the final day of competition for me, as one massive favorite, Kenya’s Timothy Cheruiyot, will try to stave off a barrage of challengers that include a plucky 19-year-old, two former Olympic champions, and a guy with a mullet.
