Morning all, first post. I'm sure this has been covered before but couldn't see anything obvious using the search function.

I've been road running regularly for a couple of years but would like to spend more time on the local hills and trails. My club regularly have group runs off road and I occasionally do them, we also have a cross-country league where the courses are very hilly. My technique lets me down though. I struggle uphill as I'm fairly heavy for mountain running at around 13 stone but I'm getting better descending helped by buying decent shoes. The one thing I really struggle with is running on the deep, narrow, rutted sections we get (especially on the more peat based surfaces). These are often on the flatter sections where I should be able to run faster but I just get in a tangle. Does anyone have tips or techniques for altering running style to make this easier?
