I've decided to try C25K again, now I have the right shoes from a respectable shoe shop I've also started a Family Membership at a local gym.
I'm thinking doing C25K on a treadmill rather than outdoors will help me;
1. Control my speed better, I'm always going too fast.
2. Remove any weather excuses.
3. Remove any obsession I previously had with Strava.
Is it possible to do the C25K on a treadmill, I'm thinking about alternating the walk and run part - it's been years since I used one... do I just change the speed? If yes I assume the recommended speeds will vary per person based on size, but what works for others?
