I've noticed a few peeps on here citing niggles, aches and pains in their legs. Do yourselves a favour and if you can afford to, purchase a foam roller. These things are EXCELLENT for ironing out creases, niggles and aches on your legs. Now admittedly when you first use them it F****NG hurts like hell!! But use it well (and google some youtube vids to see how) and you'll find that the foam roller will be your friend and good bit of kit to have in your locker.
Here's a cheap one amzn.to/2xsj7I4 . There are various others if they take your fancy.
Just thought I'd mention it!
Happy running folks.
