>>201532715 miles one way as a daily commute is a tall order if you're not already an in shape cyclist. If you give yourself ample time you'll certainly be able to complete it, but you'll never be able to sustain it.
Id recommend
1) start cycling more with your shitty bike. Just ride man don't worry about distance, keep it 1-5 miles. Just ask yourself "what would it be like if i biked to THIS place". Learn what it's like to travel by bike, explore alternate routes you couldn't take via car.
2) get a real bike. Walmart bikes are truly awful. A used road bike will take you soooooo much farther so much more efficiently
3) Pick one day in the near future and just bike to work. See first hand how hard it is. Hopefully by now you've ridden at least 20 miles in one go. Just make it a dedicated adventure.
Don't expect to just be able to start riding 30 miles in a day regularly, that's truly high mileage for any human. For a novice it's impossible I don't care if you're an athlete, if you aren't regularly riding you won't be able to do it. You have alot to learn about nutrition, gearing, clothing, packing for work, bike sizing and positioning. The list goes on. You should set you goals much much smaller for the time being.
If you aren't gonna read all that, get a better bicycle and start riding smaller trips.
