This is a leftover post from last week ---
On Thursday I did a 3K fartlek at the outdoor track (! it was unlocked!). But...sadly, the workout was terrible. I was really slow, felt like sludge, and my HR was low. Just one of those bad workout days. I was supposed to do 5K but quit at 3K, at 18:25 (!so slow!). HR was only 158.
