Not sure where all the suspicious performances are. A few fast 5000m times but certainly several of those were to be expected if you got good pacing and conditions leading into the OG.
The womens 1500m times were quite quick but this event has been quite weak over the years.
Pearson is a strongly built lass but certainly has no indication of steroid use. She is fast over the flat and a beautiful technical hurdler. Her 100m times are not so fast to indicate anything out of the ordinary. Her fast hurdles time last year was a technically perfect race.
