I dont know you bud, but heres some gret advice that people in this country shudder at, as if its a sign of weakness, but in other countries its the norm.
If you have a reaccuring sports injury, go see a sports therpist.
If you have a thought injury, go see a brain therpist.
Being in a realationship is a marathon 4sure, and you have to break through many physical and psychological walls to do a marathon.
Sometimes your injury could be to bad in the long term to run a marathon and you'll have to pull out of the race, sometimes your wearing bad trainners.
I'd highly suggest a therpist for stuff like this. My best mate is one and she can help explain **** I can't and also provide a refreshing drink of water when im running to hard uphill.
Hope this helps.
