Boston Marathon Training: Weeks 5 & 6

Mastermind Weekend 1/16

Hey there!

I'm Tina

I’m the owner of Carrots ‘N’ Cake as well as a Certified Nutrition Coach and Functional Diagnostic Nutrition Practitioner (FDN-P). I use macros and functional nutrition to help women find balance within their diets while achieving their body composition goals.


An in-depth, 4-week reverse dieting course for women who feel like their metabolism has slowed down, think they might have hormonal imbalance and can’t lose weight no matter what they do.

The snow definitely put a damper on my marathon training these last couple of weeks, but if there’s a will (and a treadmill), there’s a way! The treadmill and I have become great friends recently.

Thankfully, last week was a “step back” week in my training, so I didn’t miss too much mileage due to snow and traveling. I’ll be in Seattle and then Minneapolis for the first half of next week, but I’m planning to do a couple of my training runs while I am away, so I should be back on track with building my mileage in week 7. Yay! Let’s do this!

Boston Marathon Training: Weeks 1 & 2

Boston Marathon Training: Weeks 3 & 4



  1. I LOVE that the plan has you only running a few days a week, with so much cross training! I like when running plans have only a few days of running, I find that I get injured less, or not at all with a few days of running compared to 6 days a week of running.

    I am curious how often are you doing an easy/step back week?

    I am so pumped you get to run Boston!

    1. The plan has 2 weeks of build up (time-wise) and one week of step back. So far (*knock on wood*) it’s been great keeping me injury-free! 😄

  2. Hi Tina,
    Enjoy your blog!
    Sorry if I missed this somewhere but wondering why
    you are no longer doing crossfit ?thanks !

  3. Maybe a little personal, but hopefully not – how do you maintain your milk supply with your increased mileage? So terrified of mine going down as I’m only 10 weeks post-partum. THANKS!

    1. I stopped breastfeeding a few months ago (there’s a few posts on CNC about it if you search the archives), but prior to that I never experienced a drop in supply. My doctor actually said exercise shouldn’t be an issue unless I was exercising 8 hours a day. Definitely talk to your doctor though! 😄

      1. @Tina: OH! Ok – sorry! I haven’t actually experienced a drop, yet – but just terrified of it happening! Staying hydrated and eating lots though…so hopefully it won’t happen 🙂 THANKS!

  4. i’m training for the jersey marathon which is a few days after the boston one this year. due to lots of traveling and weather the past few weeks, my training has also been thrown off track (pun semi-intended ;)) a bit. i’ve missed a few of my weekend long runs, but next weekend i’ll be in cali so i’m looking forward to getting in a beautiful run in napa valley B-)

    have also had some steamy treadmill sessions lately! started yasso 800s for this time’s marathon training and really curious to see if it’ll help me reach goal time 😉

    can’t wait until the temperatures get above freezing so we can finally get in some real long runs!!

  5. Hi Tina! I am sure you have your trip to Minneapolis all planned out, but if you are looking for any delicious places to eat, I would highly recommend the French Meadow for breakfast (the fruit/nut pancakes and breakfast burrito are amazing!) Other excellent choices are Pizza Luce for casual dinner or 112 Eatery for an upscale dinner. Enjoy your trip to our cold city!

  6. Nice job! I just signed up for the Chicago Spring Half in May so it’s time to get back on that treadmill! I have been doing shorter interval work during my HIIT/bootcamp classes, but I generally don’t run long distances until the weather warms up. Something about the cold makes me want to hide inside and break out the weights!

  7. Tina! I’m going back through some of your marathon training posts since I’m training for the Paris marathon on April 3. So far, I’ve been taking 1-2 rest days, running 2 basic runs of about 6 miles each with some speed work thrown in, and then a long run on the weekend. I’ve also been taking Flywheel classes two days a week. Is that too little running or does that seem to be ok? My longest run on the schedule is 20 miles, just like yours was. Any other advice would be amazing! Feel free to email me or shoot me a message on Twitter @julieverhage & julie.verhage328(at)gmail(dot)com Thanks soooo much!

    1. I think 3 runs per week is totally fine, but I’d try to make your mid-week runs longer. Maybe in the 8-ish range? I think I was doing up to 10-11 during the week (high mileage week) and it was definitely worth it. Good luck!!
