I've been running for a while, but wouldn't consider me experienced. Did quite a few 5ks last year for the first time and a recent 10k that I was pretty pleased with. I have been putting in about 16-20 miles per week and am sorry to say I'm a treadmill runner, train hard, and am fairly happy with the results thus far. Just started a 16 week 1/2 marathon training plan, but am considering doing one on April 1st. Too soon? Thoughts, ideas, or suggestions. Thanks.
That's pleanty of time to prepare for a 1/2. In fact, that's enough time to prepare for a full. It's just a matter of getting used to the long miles. You're not planning on doing all of your training via treadmill, are you? There is the vast difference between the treadmill and road running. But, if you have a training system set up, just follow it - those usually work for 'most' runners.
Just make sure you can break through the time barrier to be running for longer than a 10k. It took me a while mentally to do this. I would even say dont worry at all about the pace.. just get out, or on the treadmill, and see if you can run for an hour and 45 mins. then see about 2 hours. if you can do 2 hours, you're golden for a half marathon in my opinion even if it takes you longer than 2 hours.. the important point (to me) is pushing your horizon into a longer time period of running.
