Advice on how to start running????

Start small, think scouts pace, run a little, walk a little. Use something like mapmyrun to log all runs. It really motivates you. Keep at it, however rubbish you think you are. You will soon see results!
Plan a route which is easy. I live on a hill so planned route around running down hill. Once you start it becomes very addictive! Good luck!

Download couch to 5k app, run double is a good one. This got me from zero
fitness to running 5k 3 times a week. Going to use it again after having baby!

Check out couch 2 5k. It's a fabulous introduction starting with running a bit and walking a bit more for 20 mins... and then slowly over time the running increases and you find that you can run for 20 mins at a time... and then 30 mins... and then 5k...

Also check out Parkrun. They're free events and happen all over the UK on a saturday morning. You register on line, pitch up and run or walk a 5k course. As you get better you get quicker and quicker. I've seen lots of people running a bit and walking a bit but getting lots of support and encouragement from the course marshalls.

I started a thread a couple of years ago on here and found some other folk starting c25k. I think we all got to 5k. then I started another one a few months later for a half marathon.

It's amazing what you can achieve when you feel obliged to report back that you've been out and done it. And thye chocolate/wine after tastes sooo much better!

Good luck!

Get a decent bra and decent running shoes.

Some people love things like couch to 5k but i wasn't keen so I just went it alone building up times gradually.
