Sore ankles and shins tho -any suggestions?
It could be just lack of fitness.
Make sure your trainers fit properly, especially the toe box because your toes spread out more when running compared to walking. I go up a whole shoe size gorgeous trainers for this reason, but ensure they aren't lose around ankle when tied. You don't need expensive trainers at this point. Just ones that fit well.
After that, I think it'll just be fitness. At so soon into starting running, you won't have injured or hurt yourself just from running C25K Week 1-4 type distances.
Do you listen to the C25K NHS Podcasts or app? Because you get basic bits of training throughout the program that will help you develop good running form to avoid injury.
Try not to slam your foot down flat when running - that will send shocks up your shins and ankles. You want to land lightly and that's best done with a 'rounded' foot fall.
Imagine you are riding a bike and your feet are doing a similar movement to when on the pedals. Bend knee, raise foot and move it forward through the air, put foot down in a rounded motion (heel down to flat to toes only down) then push off your toes you move forward.
Look ahead and stand tall. Try not to 'bounce' up and down with your head and shoulders. Feet should land below your hips, don't stretch too far in your strides. Make sure you land on the middle of your foot, not to the left or right.
