The Trail des Cerfs in the Yvelines department is a comparitively easy 50k with only about 742m of positive vertical. There are some short hills but nothing extremely arduous. It is run in the Rambouillet forest, starting at La Queue-les-Yvelines where the Yvelines marathon always started.
The weather was cool (7°C) and sunny and the course was dry for the most part.
My goal was 5 hours and 30 minutes and I was able to finish in 5:13 so I was happy about my perf in this race. That was good for 74th place out of 184 runners and 8th out of 31 in my category.
