8:40AM - from F500 - 92mins as follows: 60mins easy-moderate, then 30mins of x 20/40's (20secs fast, 40secs easy), short cool-down. Legs a little tired but overall OK. Frigid day. Windy and very cold. Challenging winter. In not too long a time it will be a distant memory. I don't know about you...but when it comes to weather...I have a very short memory. One nice day and all is forgotten...sort of.
