A few weeks ago, I ran a 10k in 38min14s and last weekend I ran the Berlin Marathon in 3h15min. According to the McMillan race pace calculator, I should be quicker on both my Half and full Marathon. I tend to be very cautious with my pace on longer distance (more than 10k) and I never feel I have given 100% on these distances.
I was wondering if you could share your experience on your race/ pace strategy? How could I feel less careful with my pace? Should I do more long distance training? etc?
