It is most definitely worth it and definitely not too late.
You are not wrong though in that for the first several weeks it will be hard work, you will feel sore and depressingly for the first few weeks you will not notice much difference to your fitness levels or weight. This is when most people throw in the towel, but be strong, once you get through the first few weeks of exercise your body WILL begin to respond, you will stop feeling like you have been run over by a herd of elephants in the morning, you will notice it gets that little bit easier to run between A and B, you will bit by bit start shedding weight, start to tone up, you will have more energy, sleep better and dare I say it start to get a bit addicted to it. Friends you have not seen in a while will look shocked at how well you look. It is so so worth it.
First things first, get yourself a decent pair of running shoes, you might have to shell out £60-70 for them but nothing will grind your initial forays into jogging to halt then having poorly fitted shoes that tear your feet to shreds. Get yourself to a proper running shop and ask for an assessment. They will film you for about 30 seconds running on the treadmill then check your gait in slow motion to see how your foot falls and from there they will recommend the correct running shoe for you and your budget.
Second, hop onto runnersworld website and check what events are going on in your area, sign up to a 10km race in say 4 to 5 months’ time which should give you plenty of time to train and get into shape as well as providing a focus for your exercise. There are events up and down the country every weekend hosted by local running clubs, typically you will be paying about £15-22 to enter.
Search for local running clubs, some of these can be a bit ‘hardcore’ but most are very friendly and welcome people of all abilities, I can guarantee that you will not be the only beginner when you join and you will soon find a running partner, also a great way to alleviate any flagging motivation or make sure you turn up on those evenings after a tough day and your body and mind are screaming ‘sit on the sofa’.
If there are no running clubs leave a notice down your local gym asking for a local running partner.
Forget about distance at first, your first objective is to train to the point where you can run without stopping for 30mins, that might be 1km, it might be 5km, it does not matter, if you can run for 30 mins without stopping you are fit enough to start training for a race. This might take you up to 4-6 weeks to get to this point.
Open a free account with mapmyrun.com and buy yourself a cheapo sports watch from Argos, at this stage you do not need some £250 GPS enabled uber watch.
Before and after running stretch, and stretch some more, there are lots of online resources that give sound advice as to how you can do this without hurting yourself. More experienced folk down your running club will be more than happy to help out here.
But remember, it is the first month or so that is the toughest part, when your body wants nothing to do with your new regime, when initial results are not forthcoming as quickly as you like and it is all too easy to say ‘fuck this’. Get through this initial period and you will be laughing!
Forget what you look like when you are out and about, when you are puffing your way around the block and are all sweaty and beetroot red, seriously, nobody gives a shit, at least you are out doing what 95% of people can’t be bothered to do.
Buy some big fluffy towels and a huge bottle of Radox!
Good luck
