On today’s episode, we (well Jake actually) catch up with Running Coach and Ex-GB athlete Jo Wilkinson who took on an Off The Tarmac 30 mile ultra at the weekend Each episode we will take one of your questions and Jake will answer it. Today’s question comes from Kev who is targeting a marathon next April. He wants to incorporate some cross-training into his preparations and he’d like to know how heart rate zones on the bike may differ from that when running. Jake says heart rate zones on the bike will certainly be lower than zones for running, and to expect to see them around 5-8bpm lower.  See the full show notes & resources here: http://runningwithjake.com/plodcast
