Grand Slam Track has announced its first set of Challengers ahead of its second stop in Miami from May 2nd to May 4th.

Here’s a few of the big new names who will be competing at the Ansin Sports Complex:

Timothy Cheruiyot | Men’s Short Distance

Personal bests: 1:43.11A for 800m; 3:28.28 for 1500m

In Kingston, we saw the 1500m specialists’ weaknesses exposed over 800m, which allowed Emmanuel Wanyonyi and Marco Arop to go 1-2 in the overall standings. Nuguse, the Olympic bronze medalist at 1500m and American record holder in the mile, was the top 1500m guy in the Slam but only finished sixth in the 800m. Cheruiyot has a much better resume over 800m to be able to fare better in the standings. He was third in the Kenyan National Championships last year in the 800m and only lost to a pair of guys who have run 1:44.84 or faster.

Cheruiyot’s record vs the Racers:

• Vs Cole Hocker: 3–3 over 1500m; Never raced over 800m
• Vs Josh Kerr: 5–4 over 1500m; Never raced over 800m
• Vs Yared Nuguse: 2–4 over 15000m; Never raced over 800m
• Never raced against Marco Arop

In Miami, this group will race the 1500m on Day 1 and then come back for the 800m on Day 2.

Anna Hall | Women’s Long Hurdles

Personal bests: 50.82 for 400m; 54.42 for 400m hurdles

Two events over two days for Anna Hall sounds like a breeze when she’s used to competing in seven events over two days. Last weekend at the Florida Relays, she competed in the 100m hurdles, high jump, shot put, and javelin over two days. This will be her first 400m and 400m hurdles races since June 2023 since neither event is part of the heptathlon and she was on the road back from a January knee surgery in 2024. She could be very well-suited for this double.

Hall’s record vs. the Racers:

• Vs. Sydney McLaughlin-Levrone: 0–1 over 400m hurdles, Never raced over 400m
• Vs. Jasmine Jones: 0–0 over 400m; 1–0 over 400m hurdles
• Vs. Rushell Clayton: 0–0 over 400m; 1–1 over 400m hurdles
• Vs. Shamier Little: 0–0 over 400m, 0–1 over 400m hurdles

Amber Anning | Women’s Long Sprints

Personal bests: 22.60 for 200m; 49.29 for 400m

British sprinter Amber Anning is coming off earning her first global championship individual medal with gold from a tight battle with Alexis Holmes at the World Indoor Championships. We’ll get that rematch in Miami, also reigniting an old SEC rivalry between the Arkansas and Kansas alumnae. Anning may be due for a 200m personal best in the right conditions since her indoor PB of 22.60 is now faster than her outdoor 22.66 from last May.

Anning’s record vs. the Racers:

• Vs. Marileidy Paulino: Never raced over 200m, 0–1 over 400m
• Vs. Salwa Eid Naser: Never raced over 200m, 1–1 over 400m
• Vs. Alexis Holmes: Never raced over 200m, 2–3 over 400m
• Vs. Nickisha Pryce: 1–4 over 200m, 5–4 over 400m

Andre De Grasse | Men’s Short Sprints

Personal bests: 9.89 for 100m; 19.62 for 200m

If Grand Slam Track was around in 2016, Andre De Grasse and Usain Bolt could’ve been the marquee Racers in this event group. He’s one of the most decorated short sprinters and a certified clutch performer, winning seven Olympic medals over the last three Games. However, he only reached the semifinals of both the 100m and 200m in Paris, and he’s often a slow starter to the season who rounds into form by mid-summer. This year. De Grasse opened up at the Florida Relays with a 20.32 win in the 200m.

De Grasse’s record vs. the Racers:

• Vs. Kenny Bednarek: 1–2 over 100m; 4–10 over 200m
• Vs. Fred Kerley: 4–4 over 100m; 2–2 over 200m
• Vs. Oblique Seville: 0–1 over 100m; Never raced over 200m
• Vs. Zharnel Hughes: 3–3 over 100m; 2–3 over 200m

Keni Harrison | Women’s Short Hurdles

Personal bests: 12.20 for 100H; 11.24 for 100m

Despite missing the team at least year’s Olympic Trials, Keni Harrison remains one of the most decorated 100m hurdlers of all time, as she’s the former world record holder, the current No. 2, a four-time global medalist, and a six-time U.S. champ. At 32 years old, Harrison made a coaching switch this past offseason and moved on from working with Bobby Kersee in Los Angeles to joining the ALTIS group in Arizona. The signs that Grand Slam Track had caught her attention were there, as she opened up her season with a flat 100m on March 20th. She ran 11.27 to tie her personal best and then came back in the final to lower it to 11.24. It’s hard to determine how that measures up to the field in Kingston because of how windy it was, but she’ll be well-prepared for both events.

Harrison’s record vs. the Racers:

• Vs. Masai Russell: Never raced over 100m, 2–6 over 100m hurdles
• Vs. Jasmine Camacho-Quinn: Never raced over 100m, 3–11 over 100m hurdles
• Vs. Cyrena Samba-Mayela: Never raced over 100m, 2–3 over 100m hurdles
• Vs. Ackera Nugent: Never raced over 100m, 1–3 over 100m hurdles

Claudia Hollingsworth | Women’s Short Distance

Personal bests: 1:58.40 for 800m; 4:02.96 for 1500m

Australia will double its Grand Slam Track presence in Miami as Claudia Hollingsworth joins Olympic silver medalist Jess Hull in the women’s short-distance group. The 19-year-old is No. 2 on the Australian 800m list, reached the semifinals at the Paris Olympics and then took silver in the World U20 Championships in Peru last summer. She had a good start to the 2025 outdoor campaign with a 1:59.30 for 800m and 4:05.97 for 1500m last month. Interestingly, the youngster doesn’t have much of a head-to-head history with Hull or any of the other Racers.

Hollingsworth’s record vs. the Racers:

• Vs. Nikki Hiltz: Never raced each other
• Vs. Jess Hull: Never raced each other
• Vs. Mary Moraa: Never raced each other
• Vs. Diribe Welteji: Never raced each other

In Miami, the women’s short distance group will race the 1500m first on Day 2 and then the 800m on Day 3.

Tickets are available for the Miami Slam here.
