I started "running" a mile a week ago. I use quotes because I walk the first couple blocks to warm up and walk the last several blocks to cool down, and the entire route is just over a mile. On day 1, I jogged for a couple blocks at a time, walking for rest in between. I definitely walked more than I jogged.
This morning, I jogged more than I walked, and almost jogged the entire distance between warm up and cool down.
I haven't decided yet if I will then move to doing a second lap or if I will instead work on speed.
Either way, the daily habit has been surprisingly enjoyable, even if I'm very out of shape. The progress is addicting.
If you have the time I recommend working on distance first. Running farther is great for fat loss & cardio training and speed only really matters if you're trying to be competitive in races or have to squeeze your run into a confined time slot.
I also find that adding distance makes it easier to improve time. If I can only run 1 mile, it's pretty hard to run that same mile but faster. BUT if I can run 3 miles, it's a bit easier to run 1/3 of my normal distance but focusing on pushing the pace.
We can try 10 yards faster and then repeat.
As-long-as we gradually increase our effort.
Somedays walk, somedays jog, somedays shorter, somedays longer — it's all good.
I was here about a year ago. Getting close to doing 5k 4 times a week, but the last 2k are more walk than run. I'm definitely more interested in getting endurance over speed, but both improve pretty steadily at this point. I guess once I'm doing 5k without walking I'll try to just increase pace. Pretty amazing how much better my quality of life is since exercising seriously for the first time in my late 40s.
I was you like 3-4 months ago. Part walking, part running. It was a tough start and I was extremely sore during many runs!
Keep it up though. All of a sudden it all sort of comes together. I just ran 9 miles straight last week! I was shocked and so excited.
The cool thing about running and lifting weights is that you see a lot of progress early on. The path to a sub 30 minute 5k is all about getting out the door and consistently running a little more. Pretty much everyone who starts weight lifting has a moment a few months in where they go to lift a random household object and are shocked by how light it feels.
Don't push yourself too hard, especially if you are out of shape.
I did the same thing but kept pushing harder because my muscles could keep up and I wanted to build up cardio endurance, but I didn't take into account my bones.
Shin splints are no joke and will sideline you for months without warning. It takes several months for your leg bones to build up the compressive strength to deal with continuous high impact running.
Even if your endurance can take it, take your time. Slow and steady wins the race.
