My commute is just under 25 miles each way. It will take me between 1 hour 20 to about 1 hour 50 depending on which bike I take and how I feel that day. I do generally push myself and a slower ride averages 15-16 mph and if I've got good energy it will be a little over 18 mph. I've been using a Wahoo Bolt for about a month now and I use it with cadence, speed and heart rate monitors and I'm having fun with all the new data.
I had to go in today to do payroll and it was 107 degrees out! Not knowing the forecast, I went out on my go faster with only one bottle. The ride was great both ways, but had to nurse a potential bonk 8 miles from home. I think I lost about 5 pounds in sweat!
