I have been doing really easy 5k jogs on alternating days. My general physical condition isn't great right now but I still have high hopes for 2018. I'm going to continue very easy for another week or so and then slowly going to start increasing the mileage.
Anyway, the good news is that spring has reached the Korean peninsula and starting this week the weather should really warm up. That's good for the motivation even though I'm still struggling with groin pain.
