Femke Bol spotted training for 800 while wearing a bizarre mask (pics)

EPO is now available in a mist-like spray, but you have to wear a mask to properly contain it.

looks amazing in those leggings

“The 800 would be extremely painful…for you”

Pretty sure she’s jumped into advanced Pure Hate training.

Expect Great Things!!!

It’s genuinely concerning that you don’t know why she’s wearing this mask in training.

Is it? I don't know what that it. Testing CO2 or O2 levels?

You're upset that I wasn't aware of what the latest $46,000 gimmick can do for an 800 runner?

I plead guilty. When I was coaching, I was too busy taking 1:53 Hsers and having them run 1:48 as freshman while making $13k per year. I certainly wasn't up to date on the latest $46,000 gimmick

Can you please explain to me what the hell it does?

Looks like its used to measure respiration (rate and volume). At Bol's level, no possible advantage is too small to pursue in order to fine tune training.

Doing all that to run 1:58. If I Wear a mask when running 82s will I be good?

Do you have an assss like thaaaaat?

You're the journalist. Maybe you could tell us about it instead?

Maybe she needs more aerobic assistance for the 800.

looks like a vo2 master. this has been used by the Norwegian triathletes for a while now

She's so bad.

She's trying to hide her identity from her competitors....clearly failed though.

Wow, a bunch of fellow cheaters endorse/use this garbage.

Salazar used to use a bizarre mask 44 years ago.

Literally just a more advanced version of this. Baffled by the creation of this thread and most of the responses.
