A 10k buildup after a long time!

I did some buildup running
to check my pace for this Sunday's half marathon
A PB is out of the question lol
Based on today's run, if I can finish the half marathon under 5:00 pace, it'll be a huge success haha
My Forerunner 256 arrived
Many people told me to buy the 9 series
But if my 55 hadn't broken, I would have kept using it, so I'm very satisfied with the 256
It's great that features like real-time heart rate threshold and HRV, which weren't on the 55, are working well haha
Happy running everyone, the weather is humid!!
