10K a few training tips
When it comes to the 10k you'll find all sorts of people competing. From those who use it as a warm up for longer distance events to others who are competing in 10K a few training tips their first long-distance run. If you're not used to long distance running there are a few things to bear in mind when training for a 10k run.
Firstly, don't push yourself so hard that you end up injuring yourself and miss out on important training time. Learn to listen to your body and you'll be able to tell when training hard becomes training too hard. At the same time, don't cheat your body out of the preparation it needs by going easy or missing a run for the slightest of aches.
The most important thing about running is making sure you've got the correct equipment. If you've been for gentle jogs before and found that your feet were aching afterwards it's probably because your trainers just weren't suitable. Over a longer distance like 10K you'll find that inappropriate shoes can even lead to injury. Get specialist advice on buying the right trainers and you'll notice the difference right away.
What goes in your mouth is as important as what goes on your feet. You might be thrilled that all this extra exercise means you can eat a little bit more, but make sure when it comes to eating before and after running you're putting in the fuel that will help your body run and recover. Eating an hour before running is your best bet - foods high in carbohydrates help here. After a training session you'll want a mix of protein and carbs.
While it's essential that you get your body in prime condition don't forget about your mind. If you have doubts about your ability to run start focusing your thoughts on what you have already achieved to make sure you succeed. Visualise the race and crossing the finishing line: it's amazing how a positive mental outlook will transform your physical achievements.
You did not say anything about training! 10k is not a long distance, not even for an overweight newbie. Aches you mentioned come from pounding because your legs aren't got used to running. 10k takes about 30min from elite and 60min from beginner so there is no need to do a massive carboload. When you eat a hour before a race food will probably flosh in your stomach. Save that 3 to 5 hours before a race and take an easy digesting snack maybe 2h before race. Next time please provide some information about training and use your own content. That photo is likely some ultrarunner's photo - not a 10k racing/training kit.
