Hi Danny.
Be glad to help if i can? So are you doing the ride,have a break and then heading back on the same day? I will base my tips on this.... Well i don't know what preps you do usualy but for such a big milage? If you do stretching as a rule then do that,i do but some don't.Take a small bag(handlebar bag or similar) and put energy bars and the like in there for the return journey,some energy drink too). You will really need to pace yourself since you have to do the return leg too! Doing the challenge should be easy and straightforward as you are riding with the pack and the miles will fly by.... So you get to the finish line and i would imagine there's some paperwork and stuff with officials and then your free to go....(Again...
) Ok well i would use about 20 mins having a good stretch and massage your bum...
and take on loads of water and then set straight off again,if you chill for too long your legs will not want to start up!!! So now its just you riding solo which is very different from riding with a pack and you will be aware that you have reached your 'maximum' from the past.... Forget all about that and just concentrate on the road,again using a sensible pace. Now you need to set yourself some targets in your mind. This part is going to be 20% physical and 80% mental... Yes you need your legs but you need your mind to tell your legs to keep moving....
. Try and get 20 miles done before your 1st proper rest,take water on as you go. More stretching and have a bar too. 30 miles to go and you can do it a few different ways... Whatever you feel comfortable with. I would do another 10 mile and have 5mins rest and then the same again and again to the finish. If you do take energy drink i wouldn't touch them until the last 20 miles... They do work but if you have them too early you will peak too soon and feel done in!!! Another good thing would be to have friends/family waiting for you and a quick call during a break does more than red-bull to get the legs working! Just remember to cycle at a sensible pace but if you do get lucky enough with the odd downhill section then give it a bit more steam and rest as you freewheel down!!! It won't be easy mate but a little moral support down the phone and plenty of water and energy bars and a little bit of redbull i have every confidence you can do it
The very best of luck to you and i hope other members give an insight to their perspectives... What works 4 one doesn't always work 4 another!!!
