Originally got this plan and followed it to the point (3:45 pacing) for my first marathon where I aimed for a sub 4 marathon. It didn't go to plan (5:25!) but it was definitely not due to the plan. I signed up for another marathon 10 weeks after and jumped straight into the plan with some modifications. This time with a 3:44 marathon time. Way better than I could ever have hoped.
Two weeks prior to the marathon this plan also led me to a half marathon PB of 1:42 with a 12 min PB improvement.
The good:
* Great variation in the plan and it pushes you, but at the time time doesn't go too hard.
* Good exercises
* Super easy to read
* Nice encouraging messages.
What could be improved.
* I found the taper having too much volume. At the start line of the first marathon I was exhausted, but at the second time I had about 20km weeks before and during the week just 10km. This was much more appropriate and felt much more rested.
* A bit more guidance on how to modify the plan if needed. When it goes from 3 runs per week to 4 i found it hard to change rythms. An advice on how to accommodate the volume the best way possible to fit 3x would be nice. E.g. combine if needed run 1 and 3. Or alternative suggest other things like replace this run with 1h of biking in zone 2.
In the bigger perspective its the best plan i have tried, and will now buy his half marathon plan to nail the races in 2025.
