When I am a little bit down on motivation, sitting on the sofa surrounded by the "screens" and looking for inspiration, I will have a look at strava.com or bikeforums.net websites and see what is going on. People have fun, exercise and get healthy and report back their efforts, often with photos - that motivates me to get out.
On bikeforums I like to start with "Did you ride today?" to make myself feel guilty, and "Photo of the day …" to see the beauty of the outdoors world. On strava I click on the dashboard to see what I have been doing recently and then I will click on the clubs recent activities to see what other people were doing - there is always something that captures my attention, inspires me, and makes me plan my next run, ride or swim.
