I'm going on holiday on New Year's Day. 10 days of sunshine and relaxation in Egypt. This is a much needed break and I'm looking forward to it very much indeed! Here's my problem. I'm doing a My Asics Half Marathon plan because I'm hoping to run a race in May. This plan (which seems to be taking over my life by the way) tells me to do several runs while I'm away 7km to 10km. The hotel has a gym which I'm assuming will have a treadmill but I'm not that thrilled with the idea of doing much running on that. Running outside might be an option but I'm not 100% sure that I will want to be out and about too much on my own. So, what if I do a bit of exercise bike/rowing machine type stuff instead? Will that be enough to keep me going on my path towards a Half Marathon?
