I'm registered to do a half ironman on June 12, 2005. This would be my second race at this distance. I spent the better part of the winter in a fairly decent base training phase. Unfortunately, personal matters have completely haulted my training for the past 2.5 months. I am now ready to get back to training. I am wondering if it is unrealistic to prepare for a half ironman in 4 weeks. I'm not looking to go out and win or anything...just finish without killing myself. Any suggestions?
