40km commute

I increased the distance of my commute yesterday to 40km . I had to leave  about half hour earlier than  usual, it was still dark and there was thick fog but almost no traffic. It felt good to be back on my commuter bike and I made good time. I started to struggle at about the 30km mark on the way home,  I felt my hamstring getting a bit tight and stopped for a few minutes to stretch out a bit. By the time I got home I was exhausted but felt good for having done the ride, I went to bed early and slept like a log!  I’ll attempt to do the 80km return at least twice per week and see how I go!  I figure that to complete the 250km ride around the bay  it will take about 10-11hrs on the bike, so I’ll have to get used to sitting on the bike for longer periods of time. ( I just hope my butt survives!)
