I did the same for my spin miles, since the spin bikes mileage can be quite variable and unreliable. My average speed for the summer is between 16-19 mph on a mostly flat course. I use 16 mph as my "guess" mileage on the spin bike.
All bets are off trying to figure mileage for hill work-outs!!! Our hills here go from sea level to 2,000 feet, although I generally only ride to the 1200 foot level. No mountains, but a steep and long enough climb for me!

Lovey

I would do what Wongerchi suggested. As I have done the same. When The Y bought new spin bikes they had computers that would track HR, Cadence, time, speed, and miles.

I tracked my miles over the summer and the site kept my avg speed for all of my rides so I used that for a good guess. Yes my avg was 17+ mph but when the season end I was in the 19+ but i still used the 17+ avg.

Lovey:
What I do for spin or any class where I'm not on my actual bike (in other words, my 1x a week Triathlon club class) is I base my miles on a typical endurance ride.

Based on this summers riding that was ~30kph (~19mph), so I just use that.

I am in a Half/Full Ironman challenge for February on www.beginnertriathlete.com. We have to post any and all our workouts on the site. It’s an online mentorship group for us newbies and I am really enjoying it.

Half Ironman Distance:
1.2 mile swim (42.25 laps in a 25 yd pool)
56 mile bike
13.1 mile run

Ironman Distance:
2.4 mile swim (84.5 laps in a 25 yd pool)
112 mile bike
26.2 mile run

I opted for the Half Ironman option because I didn’t think I would log that many bike miles.
I know I will most likely exceed the HIM swim and run though.

Many of us live in cold climate and are not biking outside or have an indoor trainer. One of the participants local Y is doing the same challenge and their suggestions for the biking portion is this:

Spinning or group cycling class
45 minutes = 12 miles bike
30 minutes = 8 miles bike

I spin but have no idea how far I ride or could even guess. Do you think this is a good estimate? I will be getting a trainer soon but for now I need to use something.

Lovey
