B2R trailshoes

Posted on February 18, 2014 at 2:26pm 0 Comments

First customer for the  new B2Rtrailshoes in Europe.

Just ordered them this evening, and waiting now for the delivery.

Let you know about the shoes in future.

Midwinter marathon Apeldoorn Netherlands

Posted on February 2, 2014 at 1:11pm 3 Comments

Little bit disappointed about my marathon today.
Two years ago 3.45 with temp.  below zero.
Today 4.23. temp above zero 5 degrees Celsius. Till 30 k. same pace as two years ago.
 After 30 k. I think because I didn't drink enough water, there was still energy, but lot of cramps in the muscles of my legs. So running/walking. Good lesson for the future.
So this was my last race in the old B2R roadshoes, not my last marathon.
