This year will mark Boston’s 120th Marathon and the forecast is sunny and warm. If you plan to attend, we’ve gathered some links and tools to help you prepare … or if you’re an armchair observer, we have links to mobile devices, social media sites and online streaming. Remember. Marathon Monday coincides with Patriots Day, which is  a legal holiday in Massachusetts – one of only two states to commemorate the day as a holiday.
