I went for my first "run" on Monday. I've done nout prior to this.
Being the clever soul I am I decided to go straight to 10k (ovingdean to Brighton pier and back).
Horrible. Utterly horrible. I don't know how people can ENJOY this
My HIPS felt ABUSED. One the one hand I was happy to have pushed myself (probably too far too soon) but shocked at how quickly fatigue kicked in on my legs (about 6k in I was DONE).
Please tell me it gets better. I've got the half marathon in Feb!
Honestly it does get better but would recommend you look at a structured training programme for getting up to HM distance, too much too soon will just result in injury and consequent misery. Theres stacks of information out there on Runners World or in this board to suggest how you build up. Parkrun 5ks a great way to start- come and join us at Hove Park on Saturday for a start! Join a gym and do some core strengthening exercises, think about joining a running club for loads of advice.
It will get better!
