Interesting Facts and Athlete Background
• Top 2 in the world, Katie Ledecky & Sarah Sjostrom, swimming this event effectively as an off-event, while constantly flirting with the WR
• Showed Katie and Sarah are extraordinary athletes, but did not rule out the rest, packed with veterans including current WR holder
Federica Pellegrini (1:52.98, w/full body suit)
Katie Ledecky, USA
• master of distance events
• Extremely versatile across all distances (400, 800, and 1500)
• 200 free would be her toughest test
• Proven herself here before, winning Gold in 2015 World
Championships
• Known for her distance ability, can close like a freight train.
Emma McKeon, Australia
• Seemingly the underdog,
• at the time she was 4th swimmer to break 1:55 that year with
impressive Trials swims
• Comes from a family of Elite Swimmers including brother &
father who competed at the Olympics, and Mother & Uncle who
competed at the Commonwealth Games
Sarah Sjostrom, Sweden
• Unmatched sprint butterfly Queen
• Claimed World Championship title in 2013
• Proven herself multiple times in this event
• Scratched from this race at the 2015 World Championships, but
beat Ledecky’s Gold winning time in her leadoff of Sweden's
4x200 relay
• As sprinter, she can take it out fast, but can she hold that speed
Federica Pellegrini, Italy
• Decorated history in this event, including silver in Athens at the
age of 16 and Gold in Beijing,
• Smashed WR in 2009 Rome world champs, during suit era

9. Initial Lap – by the
numbers
9www.tritonwear.com
Lap winner: Emma
● Strong start, and fastest speed
Lap loser: Federica
● Early breakout, playing catchup
Strongest advantage: Sarah
● strongest start & strong stroke
Weakest disadvantage: Katie?
● Least efficient stroke with high stroke
rate and low shortest DPS – can be
effective, but hard to maintain
Ahha moment:
● Two distinct swimming strategies at play
● Ledecky is “slow” to the 50, with a less
efficient stroke, but is able to maintain

Lap winner: Katie
● Maintains speed and stroke count, increase
DPS, pull away from competition
Lap loser: Emma
● Dramatically loses speed, while maintaining
strokes
Strongest advantage: Sarah
● Increased stroke rate, while maintaining
speed and efficiency; pulled ahead of Emma
Weakest disadvantage: Federica
● The high stroke rate with poor underwaters is
hurting her as she is wasting valuable energy
Ahha moment:
● Emma’s endurance is starting to falter after
starting aggressively

15. Final Stretch – by the
numbers
Lap winner: Katie
● Finished strong with stable change in all metrics
throughout. Endurance shines through.
Lap loser: Emma
● Didn’t have the energy to increase her stroke
rate to keep pace with the rest
Strongest advantage: Katie
● Time underwater on the last leg and high stroke
rate
Weakest disadvantage: Sarah
● Increased her stroke count without impacting
speed - saw high increase of stroke rate
Ahha moment:
● Strong finish for Pellegrini – if her walls had
been stronger, she would have come 3rd

17. Overall Race Strategy
17www.tritonwear.com
Ledecky PellegriniMcKeonSjostrom
The first thing we immediately see when we dig a little deeper into the
data analysis, is there were two very distinct races happening here.
Katie & Frederica (green and purple lines) used similar strategies:
- higher stroke counts,
- lower DPS and faster stroke rates (lower number in this case
because we’re showing seconds per cycle)
Sarah and Emma (orange and yellow lines) focused on what is
typically referred to as “more efficient” strategy
- Lower stroke counts
- Higher DPS and stroke rates
This just goes to show there is not one right answer or perfect
formula for your athletes – it depends on the athlete and their
individual strengths and weaknesses – this is why it is so critical
to track your athletes to be able to give more personalized
feedback during training to get them to reach their full potential.

18. Conclusions
Katie
Strength: endurance
Weakness: higher effort output
Future training notes: increase
stroke length without losing rate
Federica
Strength: sprint on final length
Weakness: turns & underwaters
Future training notes: improve
walls to save energy
Sarah
Strength: front end speed while also
driving home
Weakness: not ramping soon enough
Future training notes: level out
pacing over the race
Emma
Strength: turns & underwaters
Weakness: endurance past 100M
Area of focus: maintain speed
while stabilizing DPS and stroke
count

19. Takeaways you can use
19www.tritonwear.com
How are your mid-distance swimmers
maintaining after the 100M mark in a 200M
race?
● What can you do to help them improve their back
half endurance?
How are your swimmers’ underwaters and
turn times affecting their total race?
● Can they make up for what they lack in stroke rate
maintenance with killer walls?
How stable is the change in metrics, length
to length?
● What can you work on to improve the stability to
help maintain any advantage gained in the
beginning of the race?
What is the weakest point in the race you
are analyzing?
● How can you help the athlete overcome this to
improve overall output?
● Can you pull from any other swimmer’s
performance playbook to help improve here?
What is the strongest attribute of the race
you are analyzing?
● Can you use this learning to help any of your other
swimmers improve?
Different athletes have different strengths –
play to them!
● It’s important to track your athletes or you won’t
find the ideal strategy for them specifically
