the benefits of cross-training on display

My long run this morning was relatively slow, even though I started right after a good night's sleep! 26.5km in 2:38hrs.
Yesterday evening I also did 13km easy run.
These days I do not do any extra biking apart from 15km to work and back. Therefore I feel stronger in running and my body doesn't mind the increased mileage. I now realize how much fitness and strength are enhanced by cross-training. Nevertheless, I will have to watch out and not go overboard!
I will keep a high mileage also this week, and then I will go back down to 100km running plus recreational biking and callisthenics.
