Great half marathon in a smallish town in Germany. Surprisingly many local and senior runners, and fast: I'm usually on the slower side, but here finished last but one in my age group. If you're above 2h, expect to bring up the rear.
Beautiful route, along the canal. In February you may still expect to see some snow and ice.
German senior legend Klemens Wittig supposedly has been seen participating here, finishing the half marathon below 2h at 85 years of age.
Half marathon. Some overlap in the routes, but clearly marked and supported. Mile markers at every km. Water stations, but basically no food/gel/electrolytes.
