March Run Totals

I've been running more and more straight and not paying as much attention to how far the walk intervals are when I do them.  So if I have walk mileage here, it's from a pure walk (and wasn't counted for my half marathon training weekly numbers).

In the month of March, these are my totals:

Run: 76.175 miles
Walk: 3.01 miles
Total: 79.185

Also, I'm going to change this a little bit to take out the straight walks that I didn't count in training for my mileage.  I'm doing enough running now I don't think I should count those.

Total Run mileage
January: 60.122
February: 61.634
March: 77.715
2012 total: 202.551

My 2011 total mileage (including walking) was 279.04.  Can I beat that by the end of April?  That's not necessarily a goal but I think I should beat it by the end of May for sure.
