Working heart rate training

[Baggy]

Just to see if it works, I'm going to try riding at 60 - 70% of my working heart rate for a month to see if it makes me any <ahem> leaner and speedier.

Has anyone actually tried this and found it worked?

I appreciate that it probably equates to winter style Long Slow Distance so there must be something in it, but 60 - 70% for me is between 120 - 140 bpm. Riding at that pace feels s-l-o-w and due to the number of hills round here it's difficult to stay in zone...

Yes.  It worked for me as long as you remember not to pig out on ice cream when you get home 

[Baggy]

erm, what if the ice cream happens half way through your route?

I don't have the willpower. I tried to take it easy on my commute home (I had a tailwind). Almost got a record commute and had an average HR of 178.

(70% is just under 160bpm. I usually average over that on a 200km Audax).

Were you watching me yesterday in Clatford?
