Key marathon mistakes:

• Going a little bit too fast too early
• Somewhat uneven pacing
• Insufficient muscle strength. Time to hit the gym!
• Lack of endurance and stamina required for significantly improving the marathon time

Key half marathon mistakes:

• There is a clear need to improve the 10K performance quite significantly
• More mental strength needed for kilometers 15-18
• Interval training sessions should probably include more 2-4km repeats (instead of 1km repeats) for better tempo endurance
• Increasing training paces too early in the season has meant "peaking" way too early in the season
