Breanna Sieracki
USA · Assigned event: Half Marathon
How this event was assigned
Assigned event is a grouping rule, not a declared specialty: the event with the highest stored 2024 World Athletics result points wins. Ties use the number of stored results, then the event name alphabetically. Missing scores sort last. An athlete can race other events; this label does not say which event they trained for. The source’s 1,100-point floor and incomplete result collection can affect the assignment.
Half Marathon: 1111 points (1 stored results)
2024 season bests

How these metrics are calculated
Each full week starts Monday in UTC. The medians use weeks with at least one stored Run. Distance is unavailable if any recorded run has missing or invalid distance. Real recorded zero distances are retained.
Run records may include separate warm-ups, repetitions, and cool-downs. Multiple records do not prove multiple sessions. Recorded run days count UTC dates with at least one Run.
Source warnings are shown, not silently excluded. Unknown or empty collections are not interpreted as zero training. No annual-week cutoff or P0 eligibility filter is used.
Calculation policy: p1-recorded-training-exploratory-v1.1. Dataset version and build date appear at the top of this profile.

Crawling back out of the sick cave 2.5 miles. Thanksgiving came with a side of a cold & the stomach flu 🫠 Lowest HRV score I've seen from my training yet: 28. Flu is gone, cold is lingering, BUT energy levels are improving. Super thankful newborn babies have such great protection through breastmilk as Lainey has been totally healthy through all of this. |
