Sha'Carri Richardson's Best Time, Ranked and Explained

What is Sha'Carri Richardson's best time and how it ranks

Sha'Carri Richardson's best time in the women's 100 meters is 10.65 seconds, set at the 2023 U.S. Championships in Eugene, Oregon, on June 24, 2023. This mark ranks as the sixth-fastest performance ever by an American woman and the 11th-fastest time worldwide for the event at the time of the run. The clock was started by an all-electric starter and recorded via fully automatic timing (FAT), with wind reading reported at +1.1 m/s, making the time fully legal for record purposes. Below is a compact breakdown of the key details surrounding that top end.

Verified 100m best and context

How the mark compares historically

Richardson's 10.65 is the fastest time ever run by an American teenager (under-20) at the time, and it surpassed the previous U.S. Championships record of 10.89 held by English Gardner. Globally, it moved her into the top tier of women's 100m performers for the season and confirmed her status as the top-ranked American for the year. For context, the world record is 10.49, set by Florence Griffith Joyner in 1988, and the top marks of 10.50–10.56 are typically run by elite global stars, making 10.65 an exceptional performance for an American woman on the world stage.

Race-by-race splits and segment performance

Below is a representative split layout for a 100m runner hitting 10.65 with a +1.1 m/s tailwind. Exact splits can vary by race video analysis, but typical elite patterns provide useful benchmarks.

Takeaways from the splits

• Fast acceleration to 30m keeps the overall time low; a sluggish start typically adds tenths.
• Maximum velocity between 30–60m is the biggest lever; elite runners sustain 12–13+ m/s peak speed.
• Speed endurance from 80–100m decides whether a good segment run turns into a personal best or a disappointment.

Technical and training factors behind 10.65

Running 10.65 requires a blend of top-end speed, efficient sprint mechanics, and robust physical qualities. Key technical traits include a tall, relaxed posture with minimal upper-body sway, aggressive arm drive that keeps elbows at roughly 90 degrees, and a quick, low paw-and-pull foot-strike pattern. Training blocks that typically support such a mark include maximal-velocity sprints, resisted and assisted sprints (e.g., sleds, bands), strength and power work focused on the posterior chain, and ample neuromuscular recovery to maintain high-quality reps. These elements collectively allow an athlete to express consistent top speed across the race distance.

How the best time fits into Richardson's career arc

Sha'Carri Richardson's best time arrives amid a career shaped by rapid ascent, high expectations, and the normal ebbs and flows of elite sport. After establishing herself as a collegiate star, she turned professional and quickly produced world-level performances. The 10.65 helped solidify her reputation as a premier American sprinter and provided a platform to compete against the world's best on major stages. Injuries, rest, and competitive planning naturally influence how often she can peak, so while 10.65 remains her fastest legal time, continued training and healthy racing will determine whether she adds even faster marks in future seasons.

Women's 100m time tiers (contextual guideline)

At 10.65, Richardson sits clearly in the world-class bracket, meaning her performances are directly comparable to Olympic finalists and global medalists. Wind-legal marks in the 10.50–10.69 range are especially significant because they indicate an athlete is capable of competing at the highest level on any given day.
