Step 1: Get a good raincover - a full bag cover - and keep it closed.

Step 2: Get an umbrellaholder on your trolley if you are using one (and of course an umbrell too)

Step 3: Under the umbrella - in the spokes - hang a towel to wipe grips (also a good place to hang spare gloves).

Step 4: Get a good rain glove - preferably more than one.
