Firstly, great forum!
Ok so I am planning to ride from London to Paris at the end of september (8 weeks away) (60 miles, then a 4 hour rest on the ferry, then another 100miles to Paris so a total of 160 miles with a 4 hour stop in the middle). Here are my vitals:
Height: 5'8" (1.72m)
Weight: 160 punds (72kg)
I've only been riding (semi seriously) for a couple of months after buying an entry level road bike (trek 1000). I'm reasonable fit - i play soccer regularly, did a marathon in April and hit the gym at least a couple of times a week.
My longest ride to date was 60 miles (3hrs 25mins in the saddle, about 4hrs 15mins in total including stops). There were some rolling hills which were pretty nasty (probably due to my lack of climbing skills!) but nowhere near mountains! In fact it was similar terrain to the 1st stage of the Tour De France which they say surprised many riders in terms of hilliness! By the end i was pretty knackered however I was happy with the time and felt my hydration/feeding was spot on, so no issues there.
Most of my other rides to date have been in the region of 1/1.5 hours, covering a distance of between 16-25 miles. (see attached)
Having done a fair bit of reading on HRM training zones I am a bit worried I am training too hard as I often find it hard to ride in zone 3, let alone 1 or 2. Using the ( i know it is unreliable) age minus formula my MHR is 190. I t seems most of my rides are at in the 80-85% of MHR zones which I have read in a few places is 'no-mans land'.
Due to work etc I can only really get long rides in at the weekends. During the week I am limited to shortish rides in the evening or more usually the gym at work during the day, which I am keen to utilise the odd hour/hour and a half I can spend in there each day. I am thinking about doing a few spin classes and maybe spending some time on the indoor ergo trainer things to maybe do some intervals / hill workouts.
Has anyone got any advice about specific workouts I could use or can see anything I am doing wrong with my training as a whole? Any advice re my training intensity would be appreciated!
