Competitive runners (myself included, once upon a time) will try almost anything that could give them a natural edge in their next 5K or 10K.
Down concentrated beet juice before a race? I've done it.
Eat chia seeds by the handful? Yep.
Altitude tents that mimic life at 10,000 feet? If only I had the money.
But new research hints that, perhaps, someday I may add consuming bacteria to that list.
