Well I've made a start! I've got say, it was rather more challenging than I expected, with the middle section (slightly uphill) being the worst part!
I've now scared myself witless by looking at other messages that talk of 20/25 min runs. It's going to have to get easier, as there's no way I could envisage doing that based on how I felt today!
Hey ho - at least the 1st one is done!
