久々のチャリトレーニング。。すこし物足りない

I suddenly had free time, so I went to Lake Tama to exercise by bicycle.
It was a little cold, but I put on a short-sleeved shirt and shorts and did bicycle exercises.

Today was a 30km workout.
As my body got used to it, I increased the speed of the bicycle a little.
It's been three weeks since my last bike exercise.

I need to do more bike exercises.
