aching calves - what shall I do??

By calves I'm guessing you mean the muscle and not shin splints. You need time off. I've roasted my quads before and needed almost a full week off for recovery before. A foam roller is nice. Another idea, find yourself a "volunteer" and a rolling pin. Have them use it on your muscles and knead out the knots. Massage breaks up the scar tissue and helps aide healing. There is no magic pill or anything you can do to make the pain go away. Ben Gay or Tiger Balm may help as a topical. Ibuprofin will help with pain and inflammation. Make sure you're eating plenty of protein to help repair your muscles. In the meantime you can elevate your legs as much as possible and ice them. If it's been a day or so and ice doesn't seem to help you can try a heating pad. Hot bath with Epsom salts. Got access to a hot tub? Use that if you can. Hot water helps increase blood flow which in turn will aide healing. Your body has to heal itself so you need to mask discomfort and aide the healing process as much as possible. I hope some of these ideas work for you as I try and do as much as possible when I have sore muscles.

I had the same thing, a sharp stab in the calves. That's bad news, you have a calf strain probably. Look it up and see if you have the symptoms. Caused by too much and too hard work. You need to rest a lot, like several weeks, depending on how bad it is. Than you can start strengthening your calves by doing calf raises. Once you can do 3x20 calf raises on each leg, pain free, you can try running. Then increase your distance very slowly and don't do any speed or hills or in your case, incline on the treadmill.
Stretching is also very important, look it up on youtube there's this stretch that you use a towel while lying on your back. Good luck and I hope you caught it early so you won't have to rest much. And add some running friends on mfp, somehow it helps morally, I'd be happy to offer my support.

Either way, I have been running quite a bit past few days

Sounds like you added way too much way too fast. You need rest, massage/foam/rumble rolling, and to ice down the muscles. Since the problem has developed only within the last few days, I suspect you have not given it sufficient time to help. Nothing can be expected to work right away, and you probably need at least a couple days off running.

When you get back to it, start with 3x/week, and don't add more than 10% to your weekly mileage per week. You can't go from zero to daily runner overnight without risking injury- as you now know. Daily runners didn't get that way inside of a week- patience will pay off in the long run. (pun intended!)

Hi all, just signed up to this website and have been trying to find horse riding on exercise search but can't find anything, can anyone advise please?

Wouldn't that go under exercise for the horse?

When an activity isn't included in the database you can add your own exercise and input the calories.

I googled "exercise calories horseback riding" and this was the first hit:

You can look it up and input it yourself.

First, don't run so hard you can't walk up stairs. Anyway, stretch out your calves right after running and right before bed that night. The next morning, give them a massage with Icy Hot. Later on, as the Icy Hot is wearing off, use a tennis ball to rub them and then do some more gentle stretching. That's what I do for ballet and it works wonders

Very cold baths. Don't worry about adding ice, there is little extra benefit. Wear a warm top and play good music while you do it. It works, promise!
