You may think your slower, fatter, weaker than everyone who keeps a journal but as wrcortese said you have more commitment and dedication than most on the forum. Look at the size of your journal compared to everyone elses.
I totally agree with you re comfort zone theres no point in staying in it, how are you going to improve. The most impressive man is the man who works on his weaknesses and not on his strengths.
By the way dont get too depressed about being the oldest guy in your squad. Last saturday at qe2 I saw a grandma training, I kid you not, in the long jump pit. She must have been 70-80 lol. She was looking pretty good too!
The sub 60 will come, and once you can do that you’ll be pretty competitive with those 13-14 year old kids
