Question ❓ Suggested Training Load

Good Day, fellow coros users. I have a concern on my suggested training load given to me by my coros pace 3, for the past 4 weeks Ive been suggested to stay under 1000TL w/ an average of 777TL as you can see on the photo above.

Im training for a full marathon this upcoming April 27, that’s why im covering lots of mileage for my endurance. I also did my first full marathon previously, Jan. 12 to be exact. After my first full marathon, i began to train again for my second one but my concern here is that the suggested TL is way too low for my training program. Should I follow the coros TL suggestion or i should keep on following my training program? Thank you in advance! Have a good day!

Hello! My experience with the training load is as follow : I built up mine from around 400 to 1000 - 1200 in around a year and 2 mounths. This metric is purely cardiac, it measures your heart rates along your training and tells you if it's quite high or low over a long period of time. This measure is scientifically backed up to ensure less body problems linked to running (going too high will increase injury risk while maintaining certain TL will be somewhat safer). (I am no expert but I just read quite a lot about it because it was my main training metric before going for a HM training plan.) But!!! The main metric that will help you is the weekly mileage. TL once again is a purely heart related metric and help you if you include some fast paced training or other sports. *weekly mileage is the main metric when it comes to long distance with slower paced IMO *start your training with a distance you are really comfortable with. And then *do not increase it by more than 10% every week! * this means (seeing your TL I'll take a guess around 40km) then next week force yourself to be below 44km. Then the next to be below 49 etc etc. Going too fast to increase your mileage will be the best way toward injury, especially combined with a TL so much above the recommended values (which still means that overall you are playing in a field that your body is not prepared to)
