I thought it might be a good idea for those of us who’ve been here a while to compose a list of tips for folk just getting started. Here’s mine, feel free to add to them…
If you can’t complete a run, don’t worry. Re-run it, or drop back a session. Don’t move on to the next one until you’re happy you’ve completed this one. Don’t get caught out thinking each "week" has to be done in a week, take as long as you need.
Don’t worry about how fast you are. Just run. It might start off being slower than a fast walking pace, it doesn’t matter. Speed will come later, if you keep at it.
Get your gait analysed and invest in good, appropriate shoes. Specialist running shops generally fall over themselves to sort you out. It might seem like quite an expense (it is), but it’s worth it.
Listen to your body. If something hurts, find out why and fix it, before you run again. Aches are inevitable, you may even get to enjoy the satisfaction of aching legs after a good run… Digressing. You will ache, that’s fine, but pain is your body’s way of telling you something is amiss, pay attention.
Fall back on the forum. Everyone has a bad run every so often. Moral support here is outstanding, use it. If you’re unsure of anything, ask. There’s plenty of folk here now that have been through it. Most more than willing to chip in an opinion or two.
