A beautiful, almost hot, sunny winter's day. Wind is getting up a bit but it certainly didn't make the run feel cold at all. In fact, it helped to cool me down.
I did my usual around PB - up Charlie, Esplanade, Rotunda, Central and Arcadia, coming back to Charlie.
I tried the ratio of 3:1 again. Not sure yet whether it is just as fast as running all the way. Will try a few more and then review it, I think.
