I have been training now for over one month. It's been going fairly well, but I feel so slow. At least I have no seen progress. I'm getting slightly faster but honestly progress has been slow. Last couple of weeks I've been doing 4 hours of swim, bike and run.
I'm finding my swim isn't so bad and I've been doing fairly well. The bike hasn't been too bad, but I've been getting these killer workouts called Isolated Leg Training. You can seem them on Trainer Road.
