Hal Higdon: Multiple Marathons (2 weeks between): This two-week Multiple Marathons training program, bridging the gap between two marathons, is only for the hard core: experienced runners who are well trained, who are able to recover rapidly. Each day I will send you an email telling you what to run and also offering training tips. For more information, look for the Multiple Marathons file on my website: halhigdon.com.
