You train for a spring marathon. As long as you follow a sensible, progressive marathon training plan (please do so), you have a long way to go, probably just over 350km in the next three months. You can also take this opportunity to explore your region. One of the best ways to do this is to integrate your zip code into the National Cycle Network website and explore some of its traffic-free routes, tours, and quiet hiking trails. It will certainly beat overcrowded sidewalks or the same racetrack in the same park.
UK Walking and Biking Charity Organization Sustrans, the pioneer and custodian of the National Cycle Network, has made a good choice and selected a selection of its favorite traffic-free turfs across the UK. Do not be afraid if you do not live near his referrals. It's called a national network for a reason.
