Thought I ought to join this thread. It will be my fourth (2013, 2014, 2015, switched to Manchester in 2016 ) Start saving now for the great shopping, special shoe editions, Boston apparel, etc. that you will see at the expo and won't be able to turn down
If you try this https://www.strava.com/athlete/training-plans/running?plan=5_k for example, you can select how many runs a week you want. A certain degree of complication is unavoidable if you want to get faster, as running the same session every time and the same quantity each week will soon bring you to a plateau.
Sorry, but I wouldn't substitute much cycling for running, since running does more in the long term that just improve cardiovascular: think of the sinews, ligaments, support muscles for the ankle, bones, etc. that remodel and get stronger over a long time. Maybe to incorporate cycling you could look at a triathlon programme but's that's outside my field.
What is you objective? If it is to improve 5k or 10 km times there are a lot of plans out there with various assumptions about starting base. In general, the most common error is to have too little contrast between sessions. Maybe now is the time to make sure easy really is easy, and look into the occasional speed session, and cut out any middle ground.
You potentially will get a lot of different answers here, just like the web. The simplest answer is pick any one pitched at a beginner level such as from https://connect.garmin.com/modern/explore/training-plan. No beginner's plan will be hugely wrong, the main thing is to follow it and you will complete. If you have difficulty choosing between many, remember you are looking for sufficient (of which there are many) not perfect (which is unknown).
