Sydney has been the face of the series, dominating both the 400m hurdles and the 400m flat in 2025.

The Grand Slam Track series, launched in 2025
by Michael Johnson, brings together top-tier
athletes in a points-based competition across
multiple events. Sydney has been the face of the
series, dominating both the 400m hurdles and
the 400m flat:
• Kingston Slam (April):
o 400m hurdles: 52.76s
o 400m flat: 50.32s
° Result: Unbeaten, 24 points, $100,000
prize.
•Miami Slam (May):
O 400m hurdles: 52.07s
° 400m flat: 49.69s (Season Best)
° Result: Again, 24 points and another
$100,000.
That’s 48 points and $200,000 in just two meets
-something no other athlete in the series has
come close to matching.
2. Unmatched Versatility
What makes her dominance more impressive is
her range:
• She is already the Olympic and World Record
holder in the 400m hurdles (50.68s).
• Now, she’s beating 400m specialists in their
own event, like she did in Miami, where she
clocked 49.69s, a time that would win gold at
most global championships.
• She’s also entering the 100Om flat, showing
that her speed is world-class even at the
shortest distances.
3. Mental and Technical Supremacy
McLaughlin-Levrone races with incredible
Composure and near-perfect form:
• Her stride pattern and hurdle clearance are
technically flawless.
