I have made the commitment to run my first half marathon in November 2013. I have been running for about 2 years and have completed a few 5k and 10k races. About 4 weeks ago I started following a half training program just to get my mileage moving forward. I did a 10 mile run this morning and am pacing just over 10 minute miles. I realize that since my race isn't until November, I may be doing too much right now and will be over-done by the time the race rolls around. Should I back off a little for the summer months, logging 3 or 4 shorter runs mixed with cross-training and weight lifting, and then bump back up in September? I would love any thoughts or experience anyone has to share!
