Detailed and effective program

I purchased the Advanced Marathon Plan. The ordering process was simple, I got access right after payment. The plan included a detailed Marathon Pace Calculator and specific Heart Rate Training Zones which were really helpful. I especially appreciated the Injury Prevention Protocol; it's something often overlooked in other plans. The content for the Peak Performance Phase was very specific and helped me structure my final weeks. Customer support was quick when I had a question about syncing with my watch. Overall, a well-thought-out program that delivered on its promises.

Consistent quality, came back for more

This was my second purchase from The 100 Day Marathon. Last year I used the Intermediate Plan. This time, I went for the Sub-3 Hour Marathon Guide. Just like before, the download was instant and all the materials, including the Strength Training for Runners and Nutrition for Marathoners sections, were well-organized. The quality of the advice is consistently high. I keep coming back because their plans work for me and are very reliable.

Great value for the price

I was looking for a budget-friendly marathon plan and found the Sub-4 Hour Marathon Guide. The price was competitive, especially compared to other coaching options. I picked it up during a seasonal sale and saved a bit. For what I paid, the content was really detailed, covered everything from Weeks 1-2 Base Training to the Tapering Guide. It felt like a worthwhile investment for my goal without breaking the bank. Definitely a smart buy.

Solid guide, minor issues

I got the 100 Day Marathon Plan. It's comprehensive, really goes into detail on the Italian Periodization. The Video Coaching Vault was useful for understanding techniques. However, some sections in the Training Manual felt a bit dense, could use more visual aids. Shipping wasn't an issue since it's digital, but the website navigation could be smoother. Overall, it's a strong program for the price, definitely felt like good value.

Hey, wondering if anyone's tried this 100 Day Marathon plan versus something like Hal Higdon's? Is it worth the extra cash?

K Karen P. 3 weeks ago
I used Higdon for my first few, they're solid. This one is definitely more intense, super structured. I found it got me to a PR way faster than Higdon ever did. If you're serious about a faster time, yeah, I'd say it's worth it.

Hal Higdon is good for getting you to the finish line. This 100 day one feels more like it's designed to actually make you *fast*. It's a different beast, more science-y. Depends on your goals, I guess.

Just signed up for the newsletter, but didn't see an immediate discount pop up. Is there usually a sign-up bonus or am I missing something?

M Michael 3 days ago
Yeah, I think I got like $10 off when I signed up for the emails. It might take a bit to show up in your inbox though, sometimes those things aren't instant. Check your spam too!

Hmm, I don't remember getting one when I signed up last year. They do have sales around certain times though, like November or January, that's when I picked mine up.
