How did I get to be here I need to ask myself. A set of circumstances both for me and OH. OH has always struggled with keeping a healthy weight and I do to some extent [she's too good a cook!]; we do quite a lot of walking.
1) we have a conversation with friends - he a life-long runner, she taking it up and getting on well having been well overweight - they talk about the virtues their exercise regime;
2) I have to go for a treadmill stress test to keep my licence to drive our over 3.5 tonne motorhome due to having a 'cardiovascular history' [2 strokes 12 years ago which left me paralised on one side and unable to speak properly (nothing new there then!)]. I think, I can do this stresstest OK now at 70, will I be able to at 73? 76? 79? We love our motorhome and I want to continue as long as possible. [Fortunately OH also drives it and has no such issues]
3) OH was starting to have problems with her knees, so took a trip to the physio. He told her to do less walking but try C25K as she would burn more calories quicker with less repetitions (and some specific exercises for her knees which are certainly helping).
Despite both being past the 'every year's a bonus' 3 score+10 we've embarked on the C25K plan. It's very early days, but we've got been out and got the kit (especially some decent running shoes) and enough motivation to have started. At the moment we are repeating weeks - me w3, OH w2; we feel there is no allowance for age in the regime - we're bound to be slower moving on than if we'd started 20 years ago, but hopefully we're doing the right thing.
Hithertoo we've been two dedicated non-runners - we'll see how we go.
