Awesome! Good to hear you're ready to push yourself again:)
Great pace!
.. and awesome that you pushed that hard without headache issues! I'd think that's pretty 'conclusive' evidence that your concussion issues from your wipe-out are behind you. Kudo's on having a cement head! :-)
Thanks guys. Yeah, I was pretty happy with how it went, and especially happy that the head wasn't bothered by pushing so hard :)
Great to see this! I set my 5K PB last year too - also in my first-ever 5K race. :)
