Hi Jof
Hey, dont worry, as you have been running for 3 months, there will be improvement, you probably lack confidence. This weekend run for 20mins, but this time a bit quicker than your normal pace. This will start the adaptation to your training. If you are getting board of the same route, then why not run it in reverse? Go to a gym, jump on a bike for 20 mins, then 20 mins power walking on a treadmill. With some imagination and veriety you will feel great. After a hard week of training treat yourself to a film, a walk, a relaxing night in etc.
Do not become stale, smile and feel good about yourself. Remember you are healthy,and active, surely this is a very positive vibe.
Have a good run tomorrow
