TLDR. My tips coming from someone who never ran a day in their life to 40-60km a week in 5-6 months.
1. Get decent shoes, I would say try Asics atleast, new balance/Nike/Puma/Addidas are decent but you want to try get proper running shoes if you want to take this a bit more seriosuly. Other options are Brookes and Saucony. Remember you rrunning kit is limited not like cylcing so spend more on shoes if you have strange feet issues like I do go to a foot DR and get them to recomend the righ SHOE and SIZE.
2. Get a nice couch to 5km running program, this is a great starting point.
3. DO NOT DO TO MUCH TOO SOON.
4. incase you missed point 3 DO NOT DO TO MUCH TOO SOON. This can mess you up big time thats why I recommend couch to 5km.
5. Get decent running clothes. MR price sprot is more than suffient here. You want proper technical tshirts and shorts. The shorts are R100-R150 shirts are R100-R150 as well. Nothing more needed here for now. I wont really upgrade these. This makes a world of difference to whick sweat etc away.
6. Warm up - Cool down and get a foam roller. Cheap one for R150 at dischem is more than sufficient. Youtube how they work will help you get through a lot of muscle pains.
7. Drink enough water during the day, during the run. When you take this more seriosuly you will get to the point of eating to run properly.
8. You can get a running/gps watch if you want this motivated me at first. I am still using my tomtom multisport. You can pick these up for a steal on OLX if you go secondhand.
9. Lastly, remember a bad run is better than no run. Keep up the effort your body is an ever evolving machine that will adapt to the new effort you are putting in.
All the best. Running has changed both my and my wife's lives for the better.
I supplement the running with gym but you dont have to my OCD personality would make me broke if I took up cyclcling so running is perfect for me.
