After stressing for no good reason about 90 seconds, I jumped up this morning ready to give it a go. I did my brisk warm up walk and dreaded the minute a lull came in the music thinking Lauras chirpy voice would appear, and then it did. I started to jog and thought, pretend its 60 seconds...you won't notice the difference...and I did it!!
I started to wince about 4 runs in, but by then I could see the end in sight.
I did it!! 90 seconds! Thank you for your support!
