Ramping up your mileage? We've got you covered with this mega running mix, full of tunes that will get you through those long runs—and may just have you singing out loud with Alicia Keys as you cruise through your miles.

Half Marathon Mega Mix is a Rockstar mix, which usually requires a paid subscription to access, but RockMyRun and AMR are giving it to you for free with code MEGAMIX

To redeem your half marathon running mix:

1. Open or download RockMyRun app on your smartphone. It's free, and you grab it here on iTunes or on Google Play for Android.
2. Log in, or create a free account if you don't have one.
3. Go to Redeem Code in the menu.
4. Enter code: MEGAMIX
5. Woohoo: Have many ho-ho-happy miles!.

For other free #motherrunner/RockMyRun collaborative mixes, head here.

If you have any issues with getting the app up or the mix to load, please contact Rock My Run on their help page; they are super responsive.

NOTE: When you start your RockMyRun usesership, you get a free trial of the entire app. Once that trial ends (anywhere between 1 and 2 weeks), however, access changes to the free version, which is unlimited streaming of mixes that are 30 mins or less. But any mix that has been redeemed via promo code, such as these AMR/RMR collaborative mixes, will always be available to you once you've redeemed it, even if you revert to the free version of the app.
