In total there were c.a 45000+ people running just this one race (all divided into different groups and start times.) But there were lots of people.
After the 3rd km it was LOTS of uphill and one of the hills is known for being super tough, but actually i ran up the whole thing and just kept going. Not feeling tired or breathe less at all. (Tip. When running up hill, do high, quick knees and work your arms. Looks stupid but works ;) you save lots of energy!)
Once I was home i began feeling slight pain in my knees, calves and alittle in my ankle. This morning it's only slight knee pain but otherwise I feel fine!!! :)
