Alright Bikers, I need some perspective.
How fast would you ride the last 10 miles (Avg Speed) Of a 50 mile ride under the following conditions:
First 40 miles of rolling hills (No major climbs, but not flats)
You worked the first 40 miles at about an average of 70 to 80% of max Heartrate(Panting but you can still talk)
No wind
No other riders
Last 10 miles is flat.

I Rode today & averaged 22.0 MPH for the last 10. for me this was good, but I want some honest perspective on where I am in my training.
46 years old, back to serious riding for 2 years.

Thanks.

Unless you only rode 18mph on the first forty. Don't understand the significance of this question. The only thing that counts is the overall average, including the rolling hills.

Sure it's easy to get a good speed on flats with no wind. I ride rolling terrain that's almost always up or down. At age 48, I'm happy if I can average over 20mph over a 40 mile course, solo.

This is exactly why I indicated the 70 to 80% of max heartrate on the first 40 miles.

Someone who can average 18 mph (working) in the last 10 miles is going to go slower in the first 40 working at 70 to 80 % of max heartrate than someone who is strong enough to ride 25 mph (in the last 10) who also works at the same effort (70 to 80 % of Max heartrate) in the first 40. The person able to do 25 after that effort is just stronger. (He/she is going to have a speed over the first 40 that is faster than the person who is only able to do 18 in the first 40)

Heartrate does measure effort, a stronger rider is either going to have a lower heartrate at the same speed or a higher speed at the same heartrate.

Hope this helps.
