No, not that type of Hybrid. You aren’t Nick Bare (neither am I) and this isn’t a Youtube documentary. What this is though, is training for a single modality specific race (running) using two primary modalities in training (cycling + running). The hard part about jumping into the world of running is that your cardiovascular system tends to improve much faster than your muscular and skeletal systems. This leaves us wanting to train more, but our legs/hips/feet may not be able to handle the load. This is especially true for people who sit all day at work, don’t have a history with running, or are injury prone.
