The chart above shows that actually I did not follow my race plan at all. Started too fast, you can see that the actual pace (red) is below the plan pace (blue). Everything worked fine until km-30 which the severe cramps kicked in.
Significant pace drops was caused by the cramps that stopped me from running although I did tried my best to recover the run whenever possible.
- More LSD up to 35k.
- Focus on hydration, including electrolyte replenishment.
- Don't start too fast.
