Don't know if folks will read this, but since it's my thread, just putting some progress in here.
Made it to the rails bike trail along the Allegheny River. Rode 6 miles up to the tunnel. The tunnels are really cool. There was a family just hanging out in the middle of the tunnel in the dark, LOL. Mom, Dad, an older boy, and a young daughter. Funny how you can hear them plain as day at the extreme ends of the tunnel. Feels so fantastic in the tunnel. I forgot to look at the temperature while I was in the middle. It was 73° while riding on the trail and by the time I remembered to look, I was already out of the tunnel and peddling and the temp was rising from 63° back to 73°.
Peddling time was an hour and 5 minutes with a few coasting rests here and there along with the easing through the tunnel and taking a rest at each end of the tunnel to grab a picture. Was peddling about 12 mph on the way up with a very slight incline and fluctuating between 13 and 15 mph on the way back with the very slight decline and getting fatigued. Sprinted the last 1/4 mile at around 18 mph staying down in the seat.
That was so much nicer than riding the constant up and down hills behind the house.
