I noticed on some rides such as Tallac-4 and Reinstein towards the end of the training I need to stop and let my legs rest for 5-10 seconds or so, before continuing the ride. My heart rate is around 140-ish and I’m not struggling to breathe, but my legs are burning so much I have a lot of trouble carrying on with the ride unless I take a brief pause.
I’m 45 years old, currently getting back into cycling after a 15 year hiatus due to work and the other life things. I used to race and ride regularly back then but never really “trained” This is my first try at structured training. I’m 76Kg and my FTP is 235 and currently on week two of the Sweet Spot Base, low volume 1.
I assume things will get better as my fitness improves, but is there any reason to or not to stop like I have been to let my legs stop crying? Any other solution I should be looking into?
