Most people quit because they start too hard. What to hold to in the first month so you keep going.
Motivation is high, the goal is too ambitious, soreness or injury arrives within days, and the habit breaks during the rest. It is not a fitness problem but a pacing problem. The goal for month one is not a time but a state: three running days a week. Hold that for a month and the rest gets much easier.
You do not need to run 30 minutes straight from day one. Run one minute, walk two, repeat ten times, and extend the running portion week by week. That is the fastest route that avoids injury. If you are too breathless to speak, you are going too fast.
Increase weekly volume suddenly and your tendons and joints take the load before your muscles adapt. A common guide is adding about 10% per week. It feels slow, but it beats losing weeks to an injury.
Shoes are the only equipment that matters. Old trainers with collapsed cushioning raise injury risk considerably. Getting fitted in a shop, where someone can watch your foot and stride, is the surest route. Track or packed dirt is easier on joints than asphalt.
Muscle soreness fades in about two days. A sharp ache in a joint or tendon is different. If it hurts while running, or the same spot hurts the next day, take days off. Running through that kind of pain turns days into weeks.
