John Abba and Nev Three peaks tandem challenge

we are going to attempt to complete the national THREE PEAKS challenge ie Snowdon Scafel Pike and Ben Nevis by using a tandem to cycle in between them , the charity's we are supporting are SENSE and COMBAT STRESS , the reason we have had to do a go fund me is because we can't link two charity's and we would like to split any funds raised equally between the two , we are using a camper van as our base so it doesn't matter how far we get each day we are not governed by getting to b+bs , we shall be funding all expenses ourselves so every penny raised goes to charity , my aim is to cover the 490 miles of cycling plus three climbs in 5 days but we are giving ourselves a week just in case , we won't be taking tandem up any mountains that's our transportation in-between climbs , I have no doubt I'll be editing this a few times over next couple of weeks
