Running gives you sore legs if you’re not used to it because the muscles are loaded eccentrically - ie while extending. Cycling uses the same muscles, but they are almost entirely loaded only while contracting - which is called concentric loading. When a muscle works during extension, it causes much more damage to muscle fibres. The muscles do adapt and get used to it, but it takes a little time. So if you only ever ride a bike, and never ever run, then the first run you try is going to makes your legs ache like crazy afterwards.
Firstly, running can help balance your muscle groups and avoid injury by working muscles that are under-developed by cycling. Over-specification for cycling is great while it works, but you’ll regret neglecting that balance if you get injured because some muscles are too weak. Running is also great for developing core strength. Basically, it can help you be all-around stronger and more robust, which you’ll value for your long-term health.
Cycling is not weight-bearing, so if it’s the only sport you do then it can lead to decreased bone density. Calorie restriction can contribute to this if you’re super strict with keeping your weight low. Why is low bone density a problem? Because it means your bones are weaker and you’re at higher risk of fractures when you crash. Supplementing your cycling with any weight bearing sport will help to increase your bone density - that could be weight training or running (or any sport involving running) to avoid these problems.
