As there is no swimming at the moment, so I am currently cycling and running lots. Cycle and run HIIT workouts on a Tues and Thurs, Wed is a recovery run and spin, very slow and very easy for both. Saturday LSD ride and Sunday LSD run. Until you have a certain level of fitness in your running, you will see it effect your cycling, due to being generally fatigued, once the fitness is there you should be able to improve you cycling. As other's have said, you need some structure with running and not just running all at the same pace. Start slow, build in intervals and hill repeats to build muscle power. Some days running really slow because you are tired is not a bad thing. Not every run has to be chasing PB's. Eventually running and cycling should compliment one another.
