Reliable support, consistent quality

This was my second purchase from here, opting for the Advanced Marathon Plan this time. I had previously used the Intermediate plan and achieved my goal. The consistency in the program's structure and the clarity of the daily programming schedule are why I keep coming back. Access to the materials was just as quick and easy as last time, which is always a plus. It's a reliable resource.

Good plan, slow support

I purchased the Intermediate Marathon Plan. The program content itself seems solid and well-structured, but I had a question about syncing with my watch and it took a few days to get a response from customer service. The plan delivery was instant though, which was good.

Comprehensive and detailed plan

I bought the Sub-3 Hour Marathon Guide and was quite impressed. The purchase process was straightforward; I got access to everything immediately after payment. The guide included the Daily Programming Schedule and specific explanations for each phase, like the Build Phase and Peak Performance. The Video Coaching Vault was a helpful addition, really clarified some of the exercises. I also found the Injury Prevention Protocol to be very practical. It's extensive and covers a lot of ground, making it feel like a very complete package for serious runners.

Thinking about getting this plan, but wondering if there will be any sales soon? Like a Black Friday thing, or maybe something for summer?

They usually have sales, yeah. I got mine during their January push, but I've seen Black Friday deals mentioned here before. Worth keeping an eye out for sure.

They do offer stuff like student discounts and sometimes have promotions around holidays, like April and September too. If you sign up for their newsletter, you'll probably get notified about any upcoming deals.
