A very dear friend of mine for nearly 30 years just emailed me a note telling me she would be in the area in Sept doing a half marathon. She just completed her first 10K. She asked if I would be interrested in joining her. I don't know if this is a realistic option for me for a few reasons....
1. I spend most of my time on the bike and use running as my cross training option and although I'm willing to trade some of my biking for running I don't want to compromise too much of it.
2. I only run a 5K currently.
3. As a working parent of a 3 and 5 year old my time to train is limited to 1 hour 4-5 times weekly.

Is this something that is unrealistic for me to even consider?
