The gender gap exists across all running distances as shown by Thibault et al (2010) study showsthe smallest margin in running events of 6.5% in the 100m but the largest difference 13.96% I the 4x100m.
Both the rider in question who rode away and the group of riders in question regarding the nandrolone tests where both high natural occurring levels and contamination were ruled out were part of Shane Sutton's squad of riders.

The performance benefits of testosterone do not discriminate between running distances.
On average males have a performance benefit of 11.2% (± 1. 25) across all running events & 19.0% (± 2.57) for all jumping events.

Olympic 100m champion & double gold medalist Marcell Jacobs "nutritionist" who immediately claimed Jacobs transformation was due to him is linked with Italian police investigation 'Operation Muscle Bound' for supplying HGH, testosterone and anabolic steroids.
Jacobs who was not currently in the AIU athlete testing pool rapidly improved his performance from a PB of 10.03s set in 2019, with a SB of 10.10s to take the Olympic title in 9.80s.
Jacobs has improved by 3% in less than 12 months at the age of 26.
