Running outdoor

I run almost every day for one hour. Today is the first day of the season that I run on a path. Before I had to run on asphalt because of the mud. I prefer to run on the paths among the fields and the trees. I hope the good weather is coming. I'm fed up of with the rain.

Excellent.  The grammar is all correct.  It is fine as written.  But, with some small changes, it would sound a little smoother (and maybe a little more American!)
