Another day

Another day, another ride. Quite a normal ride. Started in fairly heavy fog but gone by Northbourne. A -3 morning so I'm sure there will be a frost. the only different thing today was wearing my heart rate monitor. I have all the figures, just don't know what to do with them! Found though that I am almost scared of the heart rate monitor. my heart races just when I put it on! Anyway I discovered I spent 61% of my ride in Zone 3, is that good? My heart rate recovery I measured down at the lake. From 138 to 113. Pretty good I suppose. 409 kCal burned. Does that allow me a hot chocolate?
