Managed 4K on the treadmill as intervals...1 k steady, 1/2 faster, 1/2 faster still then back to 1 k steady again and repeat.
Man oh man that was HARD work!! Possibly/defo didn’t judge my pace very well and really had to dig deep for the last 1/2k 🙄
oh well you live and learn...still feel good for it though!! 😬
Happy running y’all 🏃🏼♀️🏃♂️x
