I beg to differ…..it was 13 km of serious #wintercycling with temp down to -21oC in places…..enjoyable, yes but not easy Strava 😀

Amazing sunset this afternoon….but what caught my eye first were the golden tiny specs in the water, which then washed up as a mini strand line of ice crystals-

The #HelsinkiBikeCommute may be paused for a while, but we still got out on the 🚲 for an early morning festive hot chocolate & gingerbread on the beach in Helsinki.
Looks far warmer than it was!
