Here's a recipe for a mini middle aged triathlon weekend. On Saturday take a one hour walk though the city, using streets you've never been on before. Marvel at the new streetscapes, the lovely houses, the new views. Ideally, during sunset, with a full moon rising. On Sunday take a 45 minute bike ride through the park, followed by a thirty minute swim. Add a ten minute hot tub. Helps if the weather is unseasonably warm, to appreciate the dry spell, before the rains (hopefully) begin.
